How to get to Pandaria at level 85 (Alliance) Video
In this first phase of the Mists of Pandaria beta test, Blizzard wants players to focus on lvl 1-10 Pandaren characters and level 85 new skill system.
That said, in a future beta patch Blizzard will enable access to Pandaria to test the zones. Before reading the following post, I managed to experience the Alliance in-game cutscene cinematic that introduces players into Pandaria. It’s still incomplete in this beta version and might change in future patches.
