On the third day of previews, Blizzard gave to us: Hunters, Druids, and Mages.
I don't play either of these classes, and couldn't care less....
The short version is: Hunters won't use mana or ammo anymore. Resto druids won't be running around as giant broccolis anymore. Mages get heroism.
I know atleast one mage who creamed his pants when he realized he was getting heroism.
Changed your underwear yet, Fj?
