The 1st reply is a good fit. Copy it. You need rigs. CCC is the way to go, so get 3 of those. Chances are, your skills are on the low side. You may want to consider farming L2's a little longer whilst you skill-up a bit.

Also hit up Eve Survival and read the mission details if you havent. Try getting into the habit of finding out which ships are triggers that spawn the next wave. This is also going to be very important when you start doing L4 missions. If you accidentally trigger several waves at once you're going to recieve so much incoming DPS that there is no way to tank it all.

Please do yourself a favour and stay some time in L3 missions.

DO NOT go straight into a BS and level 4, after a while. Some L3 drop nice Loot like the meta 4 HM launcher or imps. If you get bored do some other stuff like exploration or low level pvp.

It will take about 6-10 months, until you can fly a Harbinger as it was meant.

Seriously. Nothing is worse in-game than being only 'half-in' a new ship class.

I disagree. Level 4's is where you get the money to advance in this game BLAH BLAH BLAH BLAH I'M BETTER AND STUPIDER THAN ANYONE (SNIP)

I disagree. Level 4's is where you get the money to advance in this game while you let your skills accumulate for bigger goals. You do not have to fly a battleship perfectly either, as they have a huge amount of tank and are very forgiving of mistakes as long as you keep your exits open and have an option (i.e., drones) to remove fast scramming frigates from your near orbit. All it takes is learning the triggers and tricks of each mission, which eve-survival helps a ton.

A low-skilled dominix with dual LAR, cheap faction hardeners, T1 Ogres, Hammerhead II's and a civilian blaster makes a ton more ISK and scrap slow-boating through level 4's than it would ever hope to make on level 3 missions, especially if you salvage as you go, which you may as well since your gun skills probably suck anyway.

Rigs are definitely your friend, Cap Control Circuits will give you more capacitor, the nano pump increases armour repair amount

My relatively low SP Amarr alt uses this fit for lvl 3's against sansha NPC's

[Harbinger PVE]

7x Heavy Modulated Pulse Energy Beam I

10MN Afterburner I
Stasis Webifier I
2x Cap Recharger II

3x Heat Sink II
Medium Armor Repairer I
Armor EM Hardener II
Armor Thermic Hardener II

2x Medium Capacitor Control Circuit I
Medium Auxiliary Nano Pump I

5x Acolyte I
2x Infiltrator I + 1x Acolyte I

You should be able to get a constant speed tank for about 8 minutes with the armour repairer inactive and about 3 minutes of armour repair with the lasers and AB inactive

Substitute T2 items with meta 3 or 4 items if you don't have the required skills.

This is a game, not a foreign language course. You should really be encouraged to do whatever the hell you want - sure, you'll make mistakes along the way but you'll figure out where you went wrong by yourself...no bad thing, in my opinion.

L3s are the time where you really want to start fitting a T2 tank, imo. If you can-¦t yet, you might want to make that a priority.

When I was doing lvl2s making some isk salvaging I was following a corp mate doing lvl4s in a drake I think. He literally did it half afk with his Hob2s out in 10~ mins per room.
Now I finally got my drake and I'm a day off having Hob2s but right now in my T1 gear I have 160DPS + Drones (44.5) and I attempted lvl4 missions for the luls and saw yeah, it took me literally an hour to finish one mission no surprise, but at what point does it become manageable, and what point should I get in Raven?
