Great ideas, I would love to play this character. I have some critique: When you hear the spell names "Mind Flay" and "Spirit Shell", and you play/have played world of warcraft you have expectations for what those spells do when cast, spirit shell turns all healing into shields and mind flay works Azmodan's All Shall Burn. It's a little confusing when they work differently and do different things on the heroes character. Maybe there are other priest spells that translate...

"trait cannot be used if an active shrine exists." Why? Wouldn't it be better to just put a 20~ sec cooldown on the trait?
