Betas are not guaranteed to work for all

"A real beta rarely works, and when it does, it doesn't work well."

Unlike a lot of companies who invite players into "betas" that are little more than game demos of stable preview builds, Blizzard brings in players to an ever-changing process where our programmers are constantly making changes to the "guts" of the game.

What does that mean for you?

Betas are not guaranteed to work for individual players, ever. It's entirely possible that some users will receive a beta invite, only to find that they're never actually able to play it. This is simply the nature of a true beta. While we'd prefer everyone to be able to have a little fun while helping us test the content and servers, the purpose of the beta is to prepare Mists of Pandaria for launch, not to provide a gaming experience for beta testers.

Additionally, because of how quickly conditions change in a beta, it is extremely difficult to provide technical support that is specific to Mists of Pandaria issues. If it seems like the help you receive is very general in nature (update drivers, uninstall security programs, etc.) it's because the tech support staff does not have more specific information on the issue you are dealing with. Please remember that Blizzard is under no obligation to provide support for a product in beta, although we do try when possible.

All of that being said, we do hope that most of you will enjoy your sneak-peek into the game design process. Just be advised that trying to play a beta like it's a finished game will likely result in a very frustrating experience. Take care out there!
