I think you guys are not looking at your itemization the next patch. GC tweeted that they are thinking 553 n and 566 H. Add upgrades, 574. Add the occasional bloodsoaked, 580. Add epic gems. You know that we are going to cap hit/exp/mastery while gemming stam. Will you go for 1% avoidance @~1000 rating, considering that a non-avoided attack it's hitting you for 1-0,6*1,3=22% of a normal attack?
You are going to go for crit after mastery regardless of what crit does. I'm glad that you are being vocal about the first iteration, because you are going to use it. Even if it does nada for defense.
