1. Will opposite school lockouts still apply (e.g. can't have fire and water spells at the same time)?
(I hope so -- more tradeoffs make it more interesting)
2. What are you going to do about the inevitable situation where practically everyone has ranged gank and rez?
(move ranged gank to the ultimate slot for the pain school, and scale stats on rez very aggressively with skill/wisdom/staff level, I hope)
3. Are you still going to release the new schools, and if so, will you release them all at once, or one spell at a time?
(hopefully one or two skills at a time, I hope, since there's no need for the schools to be complete when released, and see my comment about soul flay >> pain)
