What classes are available in World of Warcraft?
The classes in the World of Warcraft are Warriors, Mages, Druids, Hunters, Warlocks, Priests, Paladins, Rogues, and Shamans. Please visit the Classes page for more information.
Have all the classes been announced?
Yes, we have announced all the classes that will be available in World of Warcraft at launch. However, we are also discussing ways for characters to evolve their classes through specialization, which will help differentiate them from others of the same class.

What classes can dual wield?
Rogues, Warriors, and Hunters can all learn to dual wield.

Are there any non-combat or "pacifist" classes that can gain levels from healing wounds, curing disease, "buffing," or by providing any other type of assistances to other players?
No.

Are there any sub-classes in the game?
There are no sub-classes, per se, in the game. However, players of the same class can differentiate themselves by choosing to specialize in three different trees of talents. A priest, for example, has access to talents in the holy, restoration, and shadow trees. One priest could become a "shadow" priest by specializing in shadow talents, while another could become a "holy" priest by focusing on holy talents. All classes can specialize through talents.
