They really need to put BLM at the top of the totem pole when it comes to damage. That's all it really has, and it's punished more by mechanics than SAM. They also need to reassess the 4.0 rotation situation because doing a 3.0 rotation without Blizzard IV shouldn't be nearly identical in DPS but also afford tons of extra leeway for mechanics.

And of course MCH needs help badly. I'm also interested to see what they're going to do with DRK. I wouldn't be surprised about a blood price change.
