If Hunters every got a Tanking spec. I just thought of a quick and stupid ability.
Bringing back Aspect of the Beast: "Fancy intro" which increases threat, dodge by x%, something vengeance, armor by blah, stamina by blah. Something like this would probably want Cobra Shot to be an instant cast on a 2-3 second cooldown or something. Casting and tanking doesn't seem to mesh well.
I almost feel Survival could do good for a tanking spec. It would be some insaneeee AOE threat.
But I'm a player and I would not want to play a game with my design.
