Missions & Complexes

You're only two months old and already running lvl4s, without assistance/guidance. That is what you are doing wrong. Continue running level 3s and training your support skills or run LVL4s with a mentor.

How are your support skills for cap and shields?

Why is your corp not helping you?

The general rule of thumb is that you should have 1000dps combined tank and gank. How are your stats?

Flux coils are generally not recommended. Also, mixing of active/buffer tanks is generally not recommended.

All of them
I would concentrate on the energy and shield skills first.
Consider utilizing an MJD to gain range as a damage mitigation tactic.

Shield Emission Systems doesn't matter. It's for shield transporters (Logistics).

Get these as soon as possible:
Energy Systems Operation 5
Energy Management 4 (go for 5 later)
Shield Compensation 4
Shield Management 4
Shield Operation 5
Tactical Shield Manipulation 4 (for T2 active hardeners)
Cruise Missiles 4
Missile support skills to 4 (including Guided Missile Precision)
Weapon upgrades 4
T2 drones!

T1 drones have tank made of paper. Don't send drones to attack targets at long distance. Kill frigates with drones when they are orbiting you. As soon as NPCs switch to your drones recall them and wait before launching them again if needed. Don't keep your drones out if you don't need them.

And what guy above said about EVE Survival.

I generally run with shield extenders and simply tank damage. But people seem to suggest that you can't passive tank on a battleship.

as a general guideline:
* Install EveMon.
* Import your Raven, import your toon
* Compare the "all 5 skills" with yours, also Tech 2 the ship on a new fit and compare.

I did exactly what you did, and running missions was harsh, especially when sometimes you cant even break tank on special ships.

Eve is a massive numbers game, imho, in missions PvE, unless your at least doing 75% of an "all 5" you will struggle. Again, as a guideline. Even with a mid Drake fit, and patience, you can take a few hours and run an L4, its just painful.

That one with Large Shield Extender is PvP fit. PvP fits don't work in PvE even if mixed in PvE fits. Also those are base on old Raven.

Use a MJD and 99% of the npc's will never ever hit you....

The reason I'm rushing for level 4 missions because I'm really looking at that 40m an hour.

Guide Missile Precision, that's really important for missiles.

I ran a Caldari Navy Raven with T1 cruise missiles and a T2 tank, so I know what you're going through. All the advice above is pertinent and excellent. Here are some specific things to think about:

You'll not achieve 40m per hour until your tank and gank are much better. I often had to warp out of missions to repair shields or rebuild cap and right now you must have to do that 2 or 3 times a mission routinely. There's no ISK made during those intervals.

Once your skills are at functional levels, your tank can consist of an X-large shield booster, a shield boost amplifier, mission-specific hardeners, and adaptive invuls.

Your drone skills need work, including Drone V. Use only light scout drones on the frigs. Hammerheads, Valkyries, etc. are too slow and will get taken out until your skills are better.

Get to Security Connections III before running another mission. Security Connection levels contribute to better missions and better rewards for those missions. You need to do this, even if you step back to running L3 missions.

I think it's awesome that you're trying L4 missions so soon. The lack of immediate success just indicates that you need the patience to build your skill set.
