Provoke = Useless?

[dark494]

I was brainstorming about this the other day with my tank friend and thought about, what if we all stack in an 8 man and I use cure III to purposely get agro for him to receive the hate value of a 1000 plus heal x8 with provoke, then I hit shroud and DPS go totally nuts not having to worry about pulling hate the rest of the fight. If one point of healing = 1 point of hate.......that would be kinda OP

1 point of healing = 0.5 points of enmity
1 point of damage = 1 point of enmity

Then add modifiers on top of this (shield oath/defiance = x2 enmity points, savage blade = 3x damage enmity points, RoH = 5x damage enmity points, etc.)
