Mercurio beat me to it, but I was gonna say the same thing. I have multiple teams, and the holy priest is simply the easiest healer to box with. one button heals the whole team, and with a clever macro, I put most of the good spells to use, and always hear that sound of the PoM zing flying around.

But definately enjoy running it as you plan, you might prefer the healer being a bit more resilient, with a self rez. (although I have had a few times when my priest dies, and the spirit of redemption saved my butt big time, because it usually hapens toward the end of a fight, and healing my palading gives him a ton of mana. Maybe i should throw in a balance druid to my team to brez the priest....)
