I've only tested 35 so far. And so far, it's pretty balanced. I've seen mages, birds, foxes, rhinos, and bears kick butt. Though, it seems as if bears have the short end of the stick. Still, the update is new and the testing I've done certainly shouldn't be considered final.

I know of others who've done 30, 51, and 61, and heard good results from them all so far.
