Over the last few days PVP

Also as a WHM, I feel I have no Identity in PVP while playing WHM.
2 cures and an AOE heal don't feel like I'm a healer.

You should see Sage, you get no heals directly, it's all done through the Kardia buff, and you have to deal damage to heal anyone. Pretty much you just slap it on yourself, and ignore the rest of the party.
