10. There are a couple of unnecessary cases of ability-bloat (although not many!). Long-duration buffs, for example, I would personally change to be passive "Auras" for all friendly nearby players, removing the need for them to be placed as hotkeys. This also sort of leads into the next point...

11. When down-scaling our character's level, why not let us maintain the use of our abilities? As far as I can tell, their effectiveness is based almost entirely on your level and equipment, so I wouldn't be overly concerned about their being too overpowered. The reason I suggest this is because I find it sort of bothersome to have to go through a mental check-list when I sync and un-sync my level. It sort of breaks up the "flow" of getting used to playing a particular rotation. This one is less minor, but as a Pugilist, I constantly forget to reapply Fists of Earth when I un-sync, and I suspect that applies to other classes, as well.
