I'd switch out [Channeling] for [Glyph of Lesser Energy] and practice managing your energy.
I never remove SoA from my skill bar. It's too good.
Remove Hex is nice, but hexes usually aren't a problem in PvE, so Cure Hex would be better cuz of the fat heal.
I'd also suggest going hybrid, bringing two or three heals. WoH or LoD as your elite, and Dwayna's Kiss and/or Patient Spirit.
So I guess your skill bar would look like this:
[Protective Spirit][Dwayna's Kiss][Word of Healing][Shield of Absorption][Dismiss Condition][Cure Hex][Aegis][Glyph of Lesser Energy]
