haha well i see multiboxing as a chance to challange myself, to be honest, anyone can go do naxx get gear, do uludar, join a pve guild and do all the raids, but when ur trying to do this on 4-5 characters, its a challange, TOC mount fight? challange for multiboxing ;0
I multibox pvp to own, and there is i guess no reason, and who doesnt want 4 guys lined up pewpewing in raids? its just do boring solo ;0
