So currently there are 11 classes in World of Warcraft (Paladin, Warrior, Death Knight, Hunter, Shaman, Rogue, Druid, Monk, Priest, Warlock and Mage)
of thouse, cloth users are: Mage, Priest and Warlock (3)
leather users are: Druid, Monk, Rogue (3)
mail users are: Hunter, Shaman (2)
plate users are: Paladin, Warrior, Death Knight (3)
so the most logical would be that the next class to WoW would be a mail user, many people have been speculating about a demon hunter class, could this be a mail user maybe? or what other class do you think should be the next one added to WoW?
