Best Healing Class in Mists of Pandaria

Healers are always a pain in the ass to take down, as all DPS know.  Healers are the backbone of arenas, and are necessary in nearly all hardcore arena comps, as well as rated battlegrounds.  Some healers, however, are vastly superior to others, primarily the priest.  The priest, with their Power Word: Shield, and copious amounts of fear, are able to not only keep their teammates up when they are on cc, but also cause immense amounts of pressure upon enemy teams with a low cooldown on their fear and dominate mind, though dominate mind is easily interrupted by anyone who is paying a slight bit of attention.  Well, at least they no longer have mana burn!
