Cool build. Haven't thought about making a hybrid spec like that, but now I'm wondering if I should do the same for PvP since I most likely won't be using Salvation.
The second build seems like a good solo build, since you can afford to not heal for the 3 seconds it takes to activate Telekinetic Wave.
As for grouping, it's difficult to say right now. I think your build would work well since you won't be using Salvation too much anyways since you need 3+ people to stay in the circle to not make it a waste of force. If you start doing raids, however, I'd considering picking up Salvation since you'll usually need to heal full time and won't be able to cast a 3 second long AoE damage ability... plus you can get several people into the Salvation circle easily.
Also, I'd personally take the two points out of Confound and put it into Pain Bearer.
