I really don't know. I'm a priest, in fact, I'm a discipline priest, I always been.
But now I look to Holy and there is Holy Nova, PoM, Pray of Healing, Heal, Flash Heal. And disc have a lot of things I didn't recognize. So now I'm thinking if only a shield is enough to make me feel like I belong to this new spec. Maybe I'm a Holy in denial. =(
