Still, nothing that doesn't happen to any other class. LoS as best you can and move if you're getting hit.
Personal advice: Just play whichever class you like most. I have all classes of healers up to level 85, shaman at 88 and druid at 86. But as you can see pally is the way for me. Priest is down at 72 so you can see which one I least like. Not to say I don't enjoy the priest, just not as much as the other healing classes.
