@zirilius: I'm an enchanter and would like to know the secrets to making bank. :(
I'd like to learn the dungeons as DPS as well, but I'm not 100 yet. Queue times for DPS are an hour long, and half the time it pops, some DPS never readies up.
But DPS never seem to have any patience for a tank learning an instance. Why rush the tank/healer? Who cares if a dungeon takes 25 minutes instead of 15?
