I know all the Cataclysm stuff is way too early to talk about. I'm confused by one item. Readiness is still in a prime location on the Marksman tree. It instantly removes the cooldowns of all your abilities except for BW. Well, that's nice. Except only a few shots have cooldowns.
In the current model, a hunter would blow all his big shots and then hit readiness and blow them all again.
In the new model, a hunter blows two big shots requiring 50 focus each and then he's at zero focus. He hits readiness and can't do anything anyway.
