This is the build im currently using and enjoy. Still in the trying to mix/max it depending what what i find and see in wfs.
My bar set up if anyone is interested: http://i45.tinypic.com/1j534i.png
In this build you have to get use to Symbol of the Torch. I put this on my Q but its one of the abilities to always be mindful that you have it. In this build SotT gives anyone i put it on a 3.2k shield.
I went into Sent for SP over Healing/absorb because SP is scaling better for the Torch. I tried a build putting more points in Healing/absorb and 0 points in SP increase and my shield was 100-200 less. My other healers were really not that much effected.
I'm very open to advice/giving tips and hope this help this is a start some of you who need help with a PvP healing spec.
