Some of these things seem pretty OP. I would be happy if they just added a root effect to it. Something like this:
Consecration
Cost: Same cost as before
Consecrates the ground around you, rooting anyone in it for 2 seconds and dealing X amount of damage over Y amount of seconds. The root effect does not break on damage.
But make the root effect something holy-ish. Keep the mana cost and the CD. For ret I want this to be a choice, for example: Do I need that mana to heal later? Or do I need the root now to kill something? It shouldn't be something you can use every CD, Blizzard likes the choice between healing, utility and damage. Holy should have a talent to decrease CD and mana cost, they need a buff.
