I stopped leveling my Druids and went back to my Shaman after seeing some of the beta videos and reading some beta personal accounts. I think Shaman are going to be, without question, the best boxing setup in Cata.

The only "random" thing added to their DPS is that Lava Burst can randomly reset. Compared to many of the other classes' catches that were added to randomize their DPS rotations a bit this is cake to deal with.
