At first glance I'd say Haste actually gets a bit devalued (due to the Rip buff). For the same reason Mastery should become even better while Crit is more or less unaffected. So I assume it's because of shitloads of Haste on gear...

Hm, ok. I haven't done any simulations yet. What change triggered this?
