I recommend Minmatar Assault. The suit skill gives you 5% sidearm clip size per level. Should give you 4 shots instead of 3. The suit also has 5 high slots at proto level, which you can use to equip 3 damage mods (supposedly after the third is not worth another) and some shield extenders or w/e you want. The suit is also the fastest mediuk suit, good for dodging LAVs and running away from tanks.

I recommend you get the ADV Minmatar Assault ASAP. Then get proto damage mods and equip 3 on the highs. Then get the ADV specialist Flaylock which has low CPU/PG cost for big damage. Finally start leveling up for the proto swarm. Equip CPU upgrade on the lows as needed.

Thanks for the advice. Got another question though. Why focus on the proto swarm last instead of immediately?

Remember, to spend sum SP into either Flux grenades (for Shield tanks and Caldari infantry) or AV grenades.

Unfortunately, Flux grenades do not affect vehicles as much as they used to. Though, they can still be used against infantry. Which, since you are using the flaylock, will lead to you doing 110% against armor, versus the 90% damage you do on shields.

Actually the Flaylock only has 70% efficiency to shields, and 104% shield headshot, I've tested in game. Making Flux grenades all that more important. I don't have the exact numbers for armor efficiency as it's difficult to look for in combat and I haven't had the chance to have a squad mate Flux himself so I can check it. I mean no offense but obviously you were guessing when posting those numbers. If anything it's probably 130% to armor which would be in line with confirmed efficiency ratings on other explosive damage type weapons such as the swarm, mass driver and locus grenades.
