I pretty much just watch to see if they use Cleric Stance.
I still focus on healing and everything, and sometimes even ignore my cohealer, but if they are going to be lazy/careful/whatever and not use Cleric Stance then i'm going to leave most of the healing to them. I pretty much heal as normal, but I'm more lenient on staying in Cleric Stance. There is nothing I hate more than a healer sitting on their hands with full MP...
