...I would like to say rogues just because locking someone in a stun to the extent that its like fighting an AFK character takes about as much skill as picking your flight path, but they obviously get kills so... Next I would point to BM Winbutton noobs but again, they get kills.... as for race.... NElf. Hands down. Look its a CLEAR WARRIOR! Bring it NElf, you'll die then run to your body so fast that you'll catch me between food breaks. 10 NATURE RESISTANCE... Counts for.. nothing....
Trolls? BERSERKER!!!!!! TO WORK I BASICALLY HAVE TO BE DEAD!!!! Blood Elf? I'LL JACK LIKE.... 150... or so... mana... 5 all resist is like blocking a punch from Mike Tyson with an infant's head. All time worst class/race combo though..? Still... a night elf.... but a PROT WARRIOR! Yea.
