I'm skeptical about this change.
I wouldn't be surprised if this is OP at first then gets nerfed back gradually as the QQ levels increase.
So we end up losing Stun, and getting a Totem that can gradually be reduced in effectiveness.
I'd be happy if Blizz got their caps on and let us Glyph for stun at least.
Not to mention how this screws over Enhancement against rogues.
