GotGame Writes: "If you don't know already, Diablo 3 is playable at BlizzCon this year. Everyone is probably dying to know about the new classes. Earlier this season, the Witch Doctor and Barbarian were announced as new classes. At BlizzCon, they also announced a third class, the Wizard. We'll cover that more in a later article. I, however, had the pleasure of trying out the Witch Doctor first hand."
