this may not go down too well on here, but here goes.
what i find in this game is the tanks pull 8-10 mobs in one hit, leaving orange circles of crap everywhere from the mobs & then run around corners so they cant be healed (los) with sometimes less than 50% health. the dps blindly following on behind the tank & so im working my arse off trying to keep everyone alive.
if by chance things may be a little slow when it comes to a boss fight, then i think ive earned the right to take a breather & get some mana back because you can be as sure as hell the tanks will be flying off to the next set of mobs before i even have a chance to roll on an item.
