PFFFFF I don't. I am struggling along in TVHM right now, because I don't have 'the right gun' and Zer0 is quite difficult if you want to be a pure-snipe build for the bosses. But since I've completed it once already I'm not too bent out of shape to ask for help when I needed it. Just when I needed to watch the plot and people dropped into my game and it went by because *other people clicked my clickies*?! ARG lol!
Drop-ins are probably the best/worst thing ever invented with multiplayer. With BL2, I'm more annoyed by ppl who tot pearl/legendary grade weapons and just annihilate everything before I even type out "skag sacks." You play BL2 on PC? If so, I'd be more than happy to help out.
