Need a reason to play World of Warcraft right now? How about this: Blizzard has started their Beta test for the Mists of Pandaria expansion. Invitations will be going out very, very soon to those with an Annual Pass, press members, fansites, opt-in beta testers, and friends and family.
The beta will initially focus on the 1-10 starting experience. Higher-level content and template characters will not be available until later beta updates. However, if you want to test the new talent system, you will be able to copy over your own characters, no matter their level.
So keep checking your inboxes for your invites!
