I tried this spec last night. It was ok, but i found myself doing alot of really close game warfronts where there were just 2 healers including myself or I was the sole healer for the team. Problem being that 95% of my time was spamming heals or my teammates would have died.
The bad thing was that on a few long fights i was going OOF and not having the 20% increase to my bubble was a very noticeable difference. I would also die pretty quickly if i got focused and wasn't guarded by the tank due to my bubble dropping so quick and inability to escape from multiple melee focusing on me.
Tonight im gonna try out my spec from the OP. At this point im just gonna focus on strait healing and it seems like my spec should "in theory" be the best option over any other hybrid or 31 point pure healing spec.
Again though thnx for the info. That other spec you posted was good just wasnt my play style. It did give me a few laughs in some practice duels with one of my friends thats an assassin. I could easily beat him in my old spec but with the one you suggested i could still nuke him down easy. end the fight with full health and not even attempt to kite or even move.
