The thing I noticed with the trees and the revamp is that it takes time to adjust, especially for me as a (decently) long-time player. Once the initial shock and horror dissipated and I could look at the classes with somewhat fresh eyes I could see what to do. Some classes are more changed than others so your mileage may vary. Rune-Keepers got off lightly (as long as you don't expect to off-heal in DPS spec) while Captains got quite a shake-down.
