As of this writing, World of Warcraft has 24 playable races for players to choose from. These races are split down the middle, 12 siding with the Horde and 12 with the Alliance. Every other expansion pack has added new races to the game; The Burning Crusade added blood elves and draenei, Cataclysm added goblins and worgen, and Mists of Pandaria added pandaren for both sides. Legion chose to add a class instead of a race, and then Battle for Azeroth added 10 new races through the allied race system, four of which came from Legion.
