Missions & Complexes

Not enough information. Which mission? What's the rest of your fit?

Shields melting isn't really an issue if you're armor tanked, but there could well be other problems somewhere in your fit or strategy.

Mission is Blockade. I only listed my defenses as that was my problem. When I warp in I basically catch all aggro from the start. Only strat I have is to burn my AB and align to safe spot in hopes to only drag a few at a time into my target range and out of the theirs. Sorry, I just got to this point so I'm not up to date on most of this.

Here's a very basic fit that will get you through pretty much any L3, AFAIK. I've never used a 'Cane, but I've used some pretty failfit Myrms back in the day; this should be up to scratch as a 0-skill level character can run the tank for 3 and a half minutes.

Change out modules for better named stuff as desired, add drones if you can. Those two hardeners get changed based on the mission enemies. A couple of links to help:

Look up your mission here and find tips:
EVE-Survival

Look up the enemy type to figure out what hardeners to run.
Eve Online NPC Damage Types

Blockade could be any of several enemy types, so you'll have to adjust hardeners as needed.

I'm at a loss. Even in my Tempest was getting same results, warp in and immediate barrage of missiles. I tried warping to 50-100 from site but it over shoots, sending me actually closer and gaining more aggro. Not even getting one BC down in my BS. I'm going to have to research and see what it is I'm not doing right. As I said, I go in and immediately align out, but the buggers are barraging me from 45m away and they all get aggro at once, over 10 of them, it's just to much. Sad because I worked my butt off to get to the 3's to make some good isk but hell, if it takes me 5 hours to do 1 mission seems better to just blitz lvl 2's. Back to researching.

Knowing who your opponent is in this mission will affect your strategy. This mission comes in several NPC flavours, and you have to fit for each different version... and not necessarily just your tanking.

From the extensive use of meta I deduce you have not invested much into armor tank skills. This does leave shield as an option. Give it a shot:
DCII 3SPR 3gyro
2LSE
Invul
AB
6 425s
2 assault launcher.
Even without good fitting and shield skills that should paste 3s. If you do have skills drop some SPRs and put on TEs.

You could try using 'Help My Mission' channel if you are still stuck, it is a player owned channel.
You can open the channel list by clicking the small speech bubble in the chat window.

Don't think I have seen a worse collection of starter fits ever.

That said, here's what I believe are the missing pieces:

1. As mentioned, you need a Medium Armor Repairer. (if you can't fit a MAR II, then look for highest Meta value)

2. Second, I bet good ISK that you did not review the mission first at a site (as given above) like L3 Mission Report You more than likely tripped more than 1 trigger and now you have an angry hornets nest to contend with. Know your enemy and win a 100 of 100 battles - in EVE, that means know your triggers!

3. A note on fittings, AC's are great when you have some skills - but it's like a ship, just 'cause you can fit 'em doesn't mean you should. New players will have abysmal performance with AC's in missions. Poor gunnery skills early on, means AC's lack punch, optimal & fall off - big fail. Use of Arty (esp. in ranged missions like blockade) will keep you from tearing your hair out and work decent enough with lower skills (big alpha helps reduce dps early on). As added bonus, esp. in a fast mover like a 'cane, range can add significantly to your overall tank.

4. Reduce hard hitting dps first, that means ignore frigs and cruisers, go for BC's first (unless they are a trigger), alternatively watch the damage reports and kill things that use weapon systems against your lowest resists.

1. Why are you worrying about shields if you're armor tanked?
2. Active tanking is required. Active hardeners and a repper. T2 pls. Remember to swap hardeners as required.
3. Methinks your biggest problem is triggers. Blockade's a ***** if you get it wrong!

+1 for passive shield Arty cane.

I've left mine behind, but it served me well for L3s. The DPS wasn't so hot, which meant I had trouble in one or two serpentis l3s due to repair, but other than those few, it pretty much walked them. Mission specific hardeners are a must. and you really want to train up to the T2 versions. those few percent make a huge difference. Invulns are nice, but if you know that you're going to be taking mostly explosive, an explosive hardener beats it hands down.

For armour, EANMs are a very different case. as you can boost them up with skills. Get those skills, as a few percent makes a difference. And get the T2 version.

Ignore the shield comp skills for now. you're not going to be using amplifiers (probably), so they'll not give you any significant bonus.
