According to the PTR, mana drain effects will now be reduced by resilience. This is complete and utter bull#*!#. With the vast majority of players sporting 400+ resilience, all mana drains will be cut back by 20% or more. And who gets *!!@ed the most? Priest? No, they still provide reliable healing, pain suppression, and power infusion. Warlocks? No, they still bring spamable cc, curse of tounges, considerable dps, and can out last anyone because life tap is ridiculously unbalanced. The real losers are hunters. We are brought to arena for one thing, and one thing only, viper sting. So you have essentially taken a class which already has troubles in arena in terms of the % of hunters who have broken the high rankings, and buffed classes which already DOMINATE the overall arena scene, especially in small scale play.
CONGRATULATIONS WARRIORS! As if you couldn't outlast teams well enough, now you're healer will run our of mana 25% slower!
CONGRATULATIONS DRUIDS! As if you weren't hard enough to oom already, mana drains do even less to you now! So instead of losing 400 mana before you shift to bear, negating the sting and continuing to regen, you now only lose 320! This buff was obviously needed, as your class as a whole is having extreme difficulty in the 2s bracket!

CONGRATULATIONS BLIZZARD! You just took an already struggling arena class and collectively kicked them in the face! But hey, warriors are only one step closer to complete arena dominance, as if that statement wasn't true already.
