On November 3, Blizzard Entertainment will unplug the Warlords of Draenor beta servers. The game will be launched officially on November 13th. Did you secure your copy of World of Warcraft: Warlords of Draenor Collector’s Edition?
Don’t wait for your local store unless you have reserved it in person or by phone. Usually game shops keep all copies for reservations, and by the time you get there at the midnight launch none are available.
