By the end of the Third War, goblins were providing weaponry, vehicles, and devious services to both the Horde and the Alliance. This wouldn't last forever.
Recently, the goblins of Kezan have found a new enemy in the Alliance – unexpected and unprofitable encounters with this faction have driven certain goblins from their comfortable neutrality. Reforging old pacts with their one-time allies, the goblins have been welcomed into the Horde with open arms.
Classes available to the Goblins are Death Knight, Hunter, Mage, Priest, Rogue, Shaman, Warlock and Warrior.
