Missions & Complexes

first port of call would be to get tech 2 sentries.

I would also switch out dcu for reactive hardener, it's great for missions and you should be able to support it with half decent cap skills.

I feel like you shouldnt need 2 repair rigs. Sentry damage rig and 2 cccs are a pretty good combo.

And finally a medium hull rep and armour rep in highs is nice to save your sentries.

As far as switching to a rattle, wait until you have cruise missile skills already--the rattle is a worse pure drone boat than the domi due to the lack of tracking/range bonuses.

For switching to Gardes, use EFT to know what the optimal on your Gardes is and switch to them around that.

Fitting guns and sentries on a domi is a major challenge, even with good skills. The navy domi is better for that (and you still need a lot of sp and some meta 8-9 things to squeeze everything in). Plus she wants a rattle.

As said already, priority is sentry 2, then shield, then cruise 1. Then the rattle become interesting.

Sustainable tank is optional with a mjd and wardens. You just need enough buffer to mjd away.

mid and lows are nice, however, highs i go with 3 Drone Link Augmentor II, 2 small remote armor rep, and a random gun. you are out of range for tractor and salvager anyway.

That is very similar to what I've been using, though I run 5 drone link augs and 1 remote rep in the highs, and removed the hardeners for drone link enhancers. I use cap rigs and a mwd for increased mobility. Overall more mobile and longer range with less tank, though I almost never go into armor anyhow.

Sometimes their is more to it than resists.

Garde have the best tracking and their higher overall damage before resists makes up for being the "wrong damage type" in some cases. There are exceptions of course like angels which are ridiculously susceptible to bouncers.

When running range scripted omnis the bonus is mainly in the fall off making boiuncers a good generic choice at long range.

I tend to pack Garde II, Bouncer II and Warrior II (for the speed and tracking).

There is also range. IIRC the sentries have different ranges with Wardens hitting out 50km base range. The garde have like 25km or something. So if fighting Serps with the MJD + DLAs snipe tactics you can instant pop cruisers at 100km with wardens once all the range bonuses stack from the Omni's. The garde struggle with much lower DPS until the rats are closer.

As to this tactic not being mobile... you don't need to be. Like a sniper you make your home at your best range and camp there picking off the enemy 1 by 1. Only frigates gangs on full tilt can make it to you in any kind of time to get under your sentries, but that's why you have defensive lights. If and when larger stuff does start to get a bit close for comfort you ShiftR your drones which instantly return and move off on MWD or if a suitable angle is available, MJD. Then pop your sentries and settle back down with the popcorn to watch the fireworks at 100km.

I have done level 4s in a Domi as discussed in this thread by others without taking a single hit point of shield damage in the whole mission and spent most of my time targeting things to keep up with the sentries which were instant popping cruiser sized rats at over 80km.

And slow to the gate? Why would you be slow to the gate? You just need to time your last MJD back to the gate so by the time you pop the last few rats it's recharged for the next pocket. The recharge time is like 3 minutes, lower with skills.

It does have it's weaknesses. You need to be certain about what you are doing if you need to AFK. These domi's do not have much of a tank and need to be flown actively and flown well. Usually outside everything else's range. Mistakes with the MJD can be costly especially with the high recharge time, but an MWDII fits nicely.

What I am taking away from this thread is that I could probably do better than 3 token rails on the highs. Armor reps for the drones and another DLA might be nice. Then I can drop the repair drones and bring salvage drones.

Any battleship with MJD can deal with L4s in short order. Here's what I used today:

[Armageddon]
Drone Damage Amplifier II

Omnidirectional Tracking Enhancer I

'Arbalest' Cruise Launcher I

Warden II x5
Praetor I x10

Mjolnir Cruise Missile x1369

The reasoning is that when MJD away to the right range (130km) my sentries don't take damage at all, so not going to lose them. Then I just sit still at this position with range scripts loaded until the rats get damage on me (shoot the nearest ship). Then I scoop the sentries and MJD to another location so that I'm 130km away. Then I repeat. If at any point I'm in range of the rats and unable to activate MJD for a while, I scoop sentries, and slowboat away with t1 heavy drones with tracking scripts. Cruises are just there to add a bit of dps on battleships, and you may replace repper and EANM for missile damage mods if you wish.
I just use this because its easy to use. No hardener switching, no large ammo expenses, no tanking, no Ewar problems, frigates are for all intents and purposes standing still. I don't even put rigs on.

To translate this into your domi, remove the tank, add more stuff to support your drone damage. Maybe even drop the AB for another sebo (scan resolution script on that one, locking range on the other) or tracking mod. Salvaging with MWD noctis after you're done is more efficient than some salvaging underways. You can also put large drone control range rigs on and drop out the drone link augmentors so you can have 5 or even 6 long range turrets (no turret bonus on domi so doesn't matter if you use lasers or projectiles or hybrids, just take what fits and what you have the skills to fire, I don't know what would be best for hitting at 130km though). Since you have plenty of low slots you can have damage mods for both drones and the turrets. 4 drone damage mods and 3 turret damage mods. Then MJD, tracking for drones and perhaps one or two tracking computer for turrets so you can boost range.

EDIT: Here's my optimized geddon fit. Copy it for the domi if you wish. With t2 sentries and t2 lasers up to skill level IV and amarr battleship V, and all fitting skills that matter, then it JUST fits with 2 CPU and 100 PG left and it has these stats:
834 dps, turrets have optimal (with aurora) at 118km, sentries at 93km but they have 69km falloff. No tank of course so keep distance with MJD and shoot the closest ship. Between 90-120km you should be doing pretty close to 800 dps. Also, you have the drone range to follow (I have 123km drone control range with this fit).
EDIT2: For reference, a paladin marauder has about 850 dps at this range without its single sentry drone.

If you have t2 cruise missiles then maybe that would be better since you can choose damage types and not chew up t2 crystals (though these beams take a long time to use a set of t2 crystals).

if you don't have sentry drone interfacing you lose 5% damage modifier and when using tech 2 drones you also get specialization bonuses which are 2% per level.

So you just sit 100 - 140km from targets and apply 600 DPS from wardens cause they are still in their damn optimal range. Your turrets does not eat additional costs for ammo and slowly chew incomming frigates so sentries keep working on big ships. Instant damage, relaxing manner. If you want different gameplay and hardcore combat action - train to Machariel, not Rattlesnake. Cause Rattlesnake will do the same job in a same way as this Dominix but for much more money and a little bit quicker. Armageddon is a good option, but it lacks bonus for drone optimal range and that is the only thing why you use Dominix. Dominix and no other ship. Once you get used to its semi/afk way of running missions, you will never sell it. Just buy Machariel for times, when you want some close combat action.

Faction sentries were buffed in the year that I was out, people probably just haven't been aware of the changes.

For people's information:

Faction sentries now all have the same range and damage modifier as T2
The way they are balanced now is by price and no increase to damage by racial drone specialisations

It does kind of annoy me as i dropped over 3 weeks into sentries but at least i get the advantages mentioned above.
