you should roll a warrior because of what we can already do...
1500 dps with an enhancement shaman/feral druid/retadin, no Improved Expose Armor, no Expose Weakness, no Curse of Recklessness, no Ferocious Inspiration, no drums and no DST. the mage who beat me by one bloodthirst crit is a frost mage with 985 spell damage/hit capped/~20% spell crit (and it's crazy easy to dps as a frost mage in a short fight... pop icy veins/trinkets/elemental, spam frostbolt, hit cold snap and do it over again. i've managed 1000 dps on my mage frost specced with ~700 spell damage/hit capped/~20% spell crit).
fixes to the new talents will come in time.
