No idea. Would be handy but you can still crunch the numbers yourself fairly easily. Yeah, I know, not fun!
I know there's an addon that breaks down all your dmg modifiers sucha s stats buffs etc. But it doesn't give you a numbe at the end? At least not an easily read number. It seems there are addons that break down all sorts of things except what you want!

I want a healing addon like DrDamage, only I want to add in mana cost per heal so I can see at a glance which heal is going to give the most bang fot the buck.
