If they're hell-bent on keeping the change, these set bonuses are a nice compromise. I have plenty of alts that effectively increasing their rested exp by 60% will be a nice shot in the arm, the increased regen out of combat sounds nice but I'd have to see how it functions, and the buff will be neat to play around with, but it'll probably end up being useful for only about half the time it's up due to most levelups happening from quest turnins.
