I feel maybe that I'm becoming to reliant on shield/flash/renew, and that I don't use Prayer of Mending and Prayer of Healing enough. Need to work on that, I think.
I would throw PoM more on the tank when available. A disc priest who is heavy on shielding (that's my style) won't really have PoM bouncing as much as a Holy priest. The shield heavy style keeps people from taking the damage needed to send it on it's way. On a bigger raid, where you cant shield everyone, it will bounce more. Still, throw it on the tank when you can. It's a heal that will help him after his shield is used up.
PoH is situational. You have it. You should be ready to use it. It's sort of the same as pain suppression, divine hymn, and desperate prayer. There are days you may not use them, and that just means you are uber and didn't need them. A lot of times I'll cast it as people are buffing up and not at full health, or at the end of a run, just cause I can.
Also, remember that Penance procs Divine Aegis and Grace. Both are really good for your tank. Edited, May 18th 2010 6:29am by dadanox
