Yea starting out at 55 is the dumbest shit I've heard in awhile. Look how many terrible DK's there were when WoTLK first got going.
i agree that its kind of stupid, but as long as you already have 1 character at level 55 then whats the big deal? Nobody wants to bother doing all that boring shit anymore, and starting at level 55 really makes people want to spend more time on the game playing one of the characters they've always wanted to have but never wanted to level.
