Big Bear Butt addresses a take on some of the new changes coming with Cata. There are definitely some interesting thoughts on the homogenization of the classes. I’ve been very optimistic along the way about all this, because as he points out, even with all the class changes, we don’t know what the fights are going to be like after, either.
As for putting it on maintenance vs revitalization, I guess time will tell. But I most definitely hope that the coming Cataclysm will be a renewal.
