Blizzard has updated their official site with a new unit from the upcoming WarCraft III: Reign of Chaos -- the Orc Shaman. Here's the juice:
Under the leadership of Thrall, the Orcs have rediscovered their ancient Shamanistic traditions. In an attempt to rid the Horde of its demonic corruption, Thrall banned the use of Warlock magic and necromancy. Now, all Orc magic users practice Shaman magic which draws its power from the natural world and the elements.
