Priest

 Stolen from WoWvault :

 Priests lead the many faiths spread throughout the disparate lands of the world of Azeroth. In Kalimdor, Night Elf Priestesses revere the moon goddess Elune, while Dwarven priests in Khaz Modan deliver the message of the Light to their people. In the ruins of Lordaeron, the undead priests of the Forsaken, their faith twisted and tainted by their tortured existences, spread a dark interpretation of the Holy Light. Regardless of their faith, however, all Priests share in their ability to manipulate the minds of those who turn to them for spiritual guidance.

Priests are the forerunner in World of Warcraft when it comes to healing and buffing. In addition, they can use either Holy or Shadow Magic to affect the minds of their opponents with spells such as Psychic Scream, which will cause enemies to flee, Mind Soothe, which reduces the range at which the target will attack, and Mind Control, which allows the Priest to control a humanoid enemy. Priests will also be able to use "Words" which are instant cast spells. Shadow Magic and Holy Magic also provide various buffs and damage spells. Priests also have some very powerful heals and get the ability to resurrect players at higher levels. The only downside at present is the fact that they wear cloth armor.
