and YES no FUCKING matter what any fuck tard dps noob says Tanks and Healers are the MOST important jobs in the game, if the aint there, idiot dps cant do shit(no dungeons no gear, no shit) and with the current dps tank do, yes a group of only tanks and healers can EASY do any dungeon WITHOUT a dps specced player, so no dps you aint really needed
PS; have done ulduar and ToC with only healers and tanks(in the current content gear) without dps'ers just to see how freaking easy it was... let me tell you this, it WAS easy without guys, no one squishy enough to die in fire or cleaves or anything.
