Rune Priest or Warrior Priest

[Azuzu]

RP + WP was pretty standard in 6 mans. WP takes care of group healing/cleansing, RP takes care of burst single target healing. They complement each other very well.

RPs starts to really shine in T3.

I chose WP for my main, the class is very fun when you have a friend who plays a tank. I really enjoy RP for pure healers, especially with their dwarf morals and tactics.

Apples to Oranges.
