There’s a whole list of changes here:
I don’t doubt we will still have a bloated spec but it does look like ice strike becoming a proc version of frost shock and the changes to flame shock having different proc versions seems pretty nice. The feral spirits being passive is also another bonus. I personally like the complete hectic version of 176 buttons to slam to be kind of fun. They are also doing some changes to totemic, which honestly still won’t make it worth playing but I could be wrong. Either way when blizzard focuses on the class you love playing and make changes in an effort to make it better, its exciting.
