I am feeling like everything is really underpowered.
What have you guys seen to be the strongest of all skills, weapons and styles so far?
Dhan shotgun is incredibly strong, but I fucking hate the way it fires. Mattock used to be one of my favorite ARs, but it's absolute garbage tier now. All the super strong skills like Omni Grenade or whatever seem to really suffer from low power cell capacity, even with skill upgrades. Melee is weak as fuck all around, I even got level IV Kett melee weapon earlyyy in the game and it still took like three hits to kill a regular mob. Even worse, I originally had a more 'fun' build, with more skills to experiment with like Annihilation, Nova, Flak Cannon, etc. but it is absolutely unplayable on even Hardcore difficulty.
I am currently running 6 Biotic Barrier and 6 Combat Passive (the tree with dmg resistance at low HP), TAC Cloak, Overload, and Singularity. It's effective enough to carry me so far, but holy goddamn shit is it boring. I tried Lance and other stuff on MP, but didn't seem to be as effective there. Might be more useful in SP.
I like the N7 Valiant and Vanquisher for Sniper Rifles, but overall most SRs are shitty. Haven't gotten to build hardly any ARs or Pistols yet, so we'll see.
