Priest group healing

[Coltimar]

Repeater regions! Cast what you want, when you want.

Remember there is a stat difference between holy and disc. If you're not having mana issues gem pure SP instead of SP/SPI or INT. SP = directly affects how much your shields absorb.

I never had mana issues with my holy priest. I use repeater regions to manually heal. The only thing I have him auto cast is circle of healing on himself when the cooldown is up. Now that my group is around 5500gs I really dont need to heal much in heroics. Even when they were just starting heroics my priest had lots of mana. I think you are blowing too many spells on auto pilot that you dont need to be casting. Try repeater regions if you have isboxer and heal when needed.
