CNR sustained tank - what am I missing?

Hi you guys.

I was setting up a CNR for lvl4 missions and came across several fits. Found my own one, fitted the thing, got into lvl4s and

WHOAH barely made it out alive.

Then I checked the numbers and found the CNR to have only 157 sustained defence in EFT (with specific hardeners and against the respective enemy damage profile). So I tried to fiddle around a little, but seriously: without 3 CCC rigs and several cap upgrades in low and mid, I just can't seem to get to the 600-700 sustained hp/s that people recommend.

Don't get me wrong, my Tengu for instance has 741 hp/s and that is with a sig radius of 150m and a 100MN fit so it makes 1.5 km/s.

I just cannot get that damn CNR up to proper values.

What am I missing? Thx already for the help!

The CNR fit I was initially using:

Caldari Navy Ballistic Control System

Pith A-Type Large Shield Booster

Is that with HP/s values or EHP/s? Depending on where you're looking at these numbers they may or may not be accurate or consider that you're not trying to tank all damage types. 600-700 hp/s recommended? That is absolutely insane... I have perhaps 250 HP/s sustained on my Maelstrom, but I kill stuff quickly enough that I don't need more. I can however maintain 1182.5 HP/s for a minute to wear down the initial aggro.

I would anyways fit an X-L boosters and pulse it instead of constantly running a large. You get the same shield per cap, but can survive a greater burst of incoming damage, instead of slowly dropping it allows you to take the high damage in the beginning.

Drop the Drone Link Augmentor as well. With the AI changes you generally don't want your drones to fight too far away, in case they get attacked. If you got Electronic Warfare Drone Interfacing you should have plenty of range on you drones.

Also in what order do you kill the NPCs? I tend to blap the battlecruisers first, as they deal a decent amount of damage but goes down in two volleys with my 800mm ACs.

EFT tells me it's EHP/s actually. I have set the damage profile to be Blood Raider, that is EM/therm, and have fit 3 specific hardeners, 2x EM and 1x therm.

The large Booster is already pulsed, cap lasts 2m:45s. Fitting an XL Booster would bring the max EHP/s up to 1000, but the SUSTAINED EHP/s remains at ~150.

Thanks for the advice with the drone link augmentor. I just had no alternative for that high slot, but that's off topic...

And my kill order is just that... BC first while drones take care of frigs and cruisers. When the BCs are gone, go for the BSs

I would say mitigating some of the damage by keeping at range from them might help. Cruise missile range is just insane, and you can target out to 93.8km (assuming max targeting range). The frigs and cruisers will still burn right after you letting the drones pick them off as they get in range. If I find incoming damage becoming too high I usually burn straight away in my turret ships, and for them it helps with tracking as well as some NPCs engage their MWD to catch up and become easy targets for both turrets and missiles.

While elite cruisers usually takes a long time to grind through with cruise missiles, if some of them are normal popping them in a volley or two might be worth it as well. They generally have a lot lower bounties so it's usually easy to spot which are elite and not that way.

I appreciate your help. But please get my question right: it is not about how I survive the missions. I could figure a lot of tactics that already helped. Pulsed active tanking needs you to pay more attention, this is clear to me and by now I can handle the missions.

I just wonder why the number of sustained defence in EFT is so low while people say it should be at least, well, a lot more.

So is it that for pulsed active shield tanks, I should not worry about the sustained value but only focus on the max defence value?

"Sustained" means, I take it, that I put the shield booster on and off and on and off so I do not run out of cap and the AVERAGE dps I receive during that whole time is the sustained defence, right?

So for the pulsed active shield tank, I get why the max defence is a lot higher than the sustained defence. But still that does not explain why my sustained number is so low while people say it should be at least 500+

1. Forget about the 500 dps tank number. You want a combined gank+tank of about 1000 - the more gank you have, the less tank you'll need. Similarily, the further away or the faster and smaller you are, the less actual soaking power you'll need.

2. get a Gist X-Large Shield Booster. X-Large has similar ehp/cap point efficiency as large, but considerably more burst, while Gist is more efficient than Pith. CNR is pulse tanked, don't even try to make it cap stable, you won't succeed without making a fail fit.

3. Drop either PDU or Damage Control (preferably both) for another BCU (and preferably Signal Amplifier II). CNR's main advantage is that one extra launcher, if you're not maxing it out, you're better off in a Navy Scorp (which btw., is a safer ship to fly if your skills aren't up to par)

4. Tengu has a better tank than CNR if it's not webbed- What CNR has going for it is its power to kill large ships fast with its more powerful long range volleys. Also, as mentioned above, distance can mitigate a lot of damage - if you're running with Signal Amplifier, you've got well over 100km target range, meaning you might want to try a fit with Micro Jump Drive now that it's available - it should really help a lot with keeping you up.

Stats like cap recharge and cap usage don't scale well when going up in ship size. Remember how you can burn an MWD forever on a frigate even on low skills, it becoming an issue on cruisers and just flatout being problematic on BS? Same thing. To make a BS cap stable on its BS size modules takes a whole lot of juggling with the modules and results in mediocre applied dps because of that. So, you either accept crappy performance OR you start fitting a cap booster. Using a cap booster means you only devote one midslot to the whole cap issue leaving all the lows for damage mods and rigs to increase applied dps. They're unwieldy to use and you can't do the half-afk thing but the net result is a high performance ship.

Then you get to the resist issue; shield suck against em/thermal (not counting T2/T3 minnie ships), they're just not good at it but your tengu gets away with it as its main resist (thermal, against Gallente) is helping you out. So you're using the wrong tanking type for the mission you seem to be doing.

Thirdly, you don't HAVE to run your tank at all all the time, or even close to all the time. Generally you get hit for low dps as the npc are still far away, then get hit more as they close in and then it tapers off again once they start dying. So in reality you might only have to fully tank for a minute or two, if at all. And if you know how that cap recharge isn't linear but peaks at 25-30% you can "ride the recharge wave" a bit, rep till your cap drops to 25%, stop your shield booster and let your cap go up to 45% or so again (which happens fast as it's close to peak) and then start shield boosting again.


But the real answer is; you're using the wrong ship. If you run into em/thermal npcs on a regular basis get an armor tanked ship or get a minnie T2/T3. In your case, especially given your name, why the hell aren't you using an abaddon, they're awesome! Buttloads of dps and enough tank to survive, not easy to use or fit but they're amazing if fitted right (most ppl fit it wrong).

Sustained *basically* means how much you can tank without running out of capacitor. I disregard the sustained number because if you have 4 min of cap with all your mods running, you're going to warp out after that anyway. Just use your max number and note how much time you have to kill npc's. If you're cap stable running missions, you're doing it wrong.

Edit: Your sustained is so low because your amount of cap is low, and you're running a big booster. So you have a high max that can run for a short period of time, after that you're screwed. Just my opinion - I like to have close to 4 mins of cap minimum and I don't like to be cap stable.

Ok thanks a lot, guys.
Both dropping the DC and PDU for 4th BCU and Signal Amp and the fitting of a Cap Booster I recognize as the Liang fit, which already seemed quite reasonable to me, but still did not solve my problem with the numbers.

I don't run into EM/therm most often, just because of the EM hole, that was kinda my worst case scenario. But yeah, I also really like the Abaddon, but yet lack both the armor rep and Laser turret skills (since I started with maxing Caldari skills).

Still to make it clear: I was only confused by the discrepancy between MY sustained EHP/s and the "recommended" numbers for lvl4 missions around on the web.

To resume what I have learned today: CNR's idea is to kill stuff quickly and drop the average DPS I receive just by that: killing stuff quickly. That means a lot of time without taking any damage at all, but also some peaks in incoming damage. So what matters for the CNR is JUST ENOUGH tank to manage those DPS peaks (warp in or new wave spawn) and next to that as much gank as possible to keep the time intervals of incoming damage as short as possible.

So my inital guess was right: for such an inhomogeneous DPS time distribution, you don't focus on the sustained value, what matters is the max defence and the gank to keep the incoming damage intervals short.

Thanks again, guys!

Yup, thing is that most people are allergic to that as it requires them to be able to realise and recognise this so most will tell you to fit for cap stability. If you have a cap life of about 3 minutes or so you're good and you can make it work, simply because your dps doesn't use cap. On a ship that DOES use cap for dps that's ofcourse a whole different story.

The closer your pve fit gets to an allout pvp fit (bar points ofcourse) the more dps you will dish out, the faster stuff will die (needing less tank) and the more isk you'll make per hour.

your tank really looks a little weak for the harder raider/sansha missions. maybe you can replace the prop mod with an ancillary shield booster for those, as you usually do not need to travel, just orbit and shoot.

I should buy an Ishtar.

Partly it was the fact you were analyzing against EM/Therm, which you recognize as being the weakness of your ship. You get really nice numbers fitting against the other pirate factions.

This is my current fit, and it works just fine . . . to the point of making most L4s boring:

Rigs. 2x rigor
1x flare

Highs: 7x Arbalest Cruise Launchers with CN missiles (I don't use tech II just to keep the fit flexible)

Mid: Pith A-type XL SB (probably could use just a T II, but I don't want to.)
CN SBA
2 CN mission hardeners
1 CN mission amp
Heavy Cap Booster II (with 15 800 charges in hold)

Low: 4xCN BCU
DC II (or sometimes a Signal Amp II)

Drones: 10 light T2

This is by no means cap stable! Only pulse the booster for one or two times here and there, not letting the shields go past half. Nor do I boost past 3/4 full, it's not needed to go to 100% every time.
This set up puts out only 640dps, the drones add 80 (only for any pesky interceptors). This is plenty for any mission. (Helps to have 33+M sp too.)

This is similiar to Liang's set up that was seen over 3 years ago.

Mission fit:

Tank is "set it and forget it". Cap stable, all you have to do is concentrate on killing stuff. Also, remember to keep moving (being a Tengu pilot, I am sure you know that).

Yes, lets use a hilariously overpriced (3 bil?) ship with a hilariously crappy low tank with no speed for the sole reason that it's cap stable. That's well worth the cost!

ie, it;s not :P

Cap Booster, haul 1 hauler full of 800s to your desired mission hub. That will end all your cap problems with 1 slot as said above.
Fit an X-Large Booster, pulse it as needed, when **** hits the fan and you need alot of tank, your cap booster will give you a very strong sustained tank for a very long time, long enough that if you haven't killed enough stuff to bring the dps down, something is wrong with you.

Me thinks you over think this... fit an XL SB with a cap booster, get BP and use salvage/loot to make new ones. I never had problems in mine when I used it. Only use your lights drones when frigs get close. with skills and implants t1 cruise missiles will deal with cruisers, except maybe angel fairly easily.

To make this fit work well you need high skills.

Ok, for the harder missions drop the afterburner and fit a hardener, makes quite a diff. Cnr pulse tank works best with a X-Large shield booster (pith X for example).

For myself , I use navy faction launchers with navy faction ammo, I prefer it to the tech II launchers and ammo. High slot I use a tractor because in some missions you have to pick up mission items and a tractor speeds that up.

The fit you are using requires max cap skills and even then its barely enough in some missions. Since you are using tech II load in precision ammo for the small stuff, drop a rigor rig or two for a CCC rig to help the tank.

If I want to kill all the ships in scarlet, this is the Battleship I use, load in all 4 types of ammo and FoF miss. Cnr may not have the most dps or the fastest, but it can do every mission out there well.

Do you have the spare grid/cpu for a cap booster? A heavy booster with 800 charges will give just about anything a high sustained tank.
