Invocation is still up in the air. Fire is still nerfed to the ground. Frost still doesn't have a useful pet. I don't know if mastery or haste will be better next patch. Can't wait to log on 2 weeks from now using a less than optimal gear setup. I'm sure my top 10 US guild would love that.
Earlier on in the PTR people just kept saying 'wait until the final build! We will know everything then!' well, friends... that time is upon us and our class is still in shambles. It's a mess that Blizzard just doesn't seem to care about.
