I will run whatever you'd like me to Theo lol. I'll be playin both the rogue and shammy pretty evenly as I couldn't decide on which I'd prefer more but I can definitely heal or tank with you through dungeons and stuff from the pve aspect. I'm flexible in whatever you guys decide.
It's completely up to you. I won't be playing seriously (or else that involves a ton of time spent practicing timing, peeling, and LOS, which isn't fun and none of us want), so it's basically whatever is the most fun.
Resto/rogue/DK can probably work (especially up to 1800 or so, we can probably duo it because everyone is so bad) and would probably be super hectic but a lot of fun. I should probably start practicing with Sub, since I think that will work best for that comp (but maybe Vendetta burst with Heroism would work better?).
In any case, I'd love to do some PvE, even if it's just buttloads of heroics.
