despite an lot of new multiboxers starting to hit heroics latley and wanting to know where to farm badges I thought I throw Fursphere a bone and try to drum up a topic for a few mutilboxers who's 'been there and done that' I've completed every heroic instance except for Mag ter and Auchenai Crypts and thought I'd ask, what have you encountered that you know you can't multibox? I suspect that blizz will be using some interesting mechanics in the 5 mans dungeons for the net expansion and it might get harder and harder for us to solo them, but what have you fellow boxers did that you know you can't complete?
