When it's released later this year, the Classic expansion will recreate World of Warcraft as it was after the original 2007 Burning Crusade expansion, which added the Outland, flying mounts, and two new races, the draenei and blood elves. Unfortunately for those hoping to experience the beloved expansion early (again) before the beta's end date, getting into the Burning Crusade Classic beta isn't as easy as starting up the game.
After a false start, Blizzard's World of Warcraft: Burning Crusade Classic beta is now officially underway.
