I tested some healing in pvp as a full healing souls as you did Kardall; except I was mainly focused on Purifier. I found it really fun with the shield and absorbs and having the hots from both warden and purifier really made it pretty easy to heal.
This is what I was using at lvl 28. http://rift.zam.com/en/stc.html?t=00jGe.0M.xxoVctd.x
I was mainly messing around with the points as I've seen some better talents being used, but it worked rather effectively for me with having the warden knockback and the HoTs as well as having shields and absorbed damage, so I could still cast heals in between.
And I mainly got the 2 points in Sent for the snare, but I think I will probably spec out of it as it seemed to really be less effective since I was mainly healing.
