TC, Zer0 is my one and only character and I can ONE HIT most enemies, even some bosses. You just have to get the right gear and setup. I didn't go for critical ascension as the enemies were all dying and I couldn't ever get stacks. I crit for millions on average. Don't listen to anyone who tells you otherwise. You just have to get the right gear, and be good at setting up your shots.

Well, sniping is the better option for me (with a proper class mod, relic, and of course, Bee), even though I got my major gamechanger for bloodshed already. Melee damage is only reliable when I'm in Decepti0n and running around naked with a depleted Love Thumper... which means death for Zer0 when he can't one shot a dude.
~22k vanilla damage for a lv50 melee hit is just so... little.
With great power comes great responsibility. Too bad I am 100% powerless, and there's nothing I can do about it.
