Topic Hows healing at 90 pvp???
Yes and no. If your team refuses to help you, it can be a miserable experience. If you have a person peeling for you, or if you are up against an idiot, it is just fine. One thing to note, both of the classes you listed are the most mobile and hard to pin down of all the healers. You should never stand there and try to heal through repeated hits to the face. That's a pally's job. If you find yourself facing hard pressure, run away.
Then run away more.
