In my opinion 31th point talent in healing tree is must have, because sometimes you just dont have enough time to heal whole group one by one, but AoE heal doing that job perfectly.
The other use of Revification is to place it under tank (with Force Bending effect) for good extra heal to aid you if tank got hit way too hard.
Electric Induction is also essential for healer, since OP already have force issues.
Only one advice in general - if OP really want to heal and to dps, just wait for dual spec patch, but until then just either heal or dps, but dont try to do both at the same time.
