How much holy to heal Outlands?

[Abira]

At 60 - how much Holy can I get away with to heal in outlands instances?

I will be levelling Prot spec, plus some portion of Holy.

13? To get Healing Light 3/3?

15? To get Imp BoW 2/2?

21? To get Divine Favor?

More?

I've been prot so far, but figured I need to satisfy both roles until heroics/endgame.

You should be fine with just 3/3 healing light. You could even skip that one and go with zero in holy, depending on your gear.

But it sounds like you are starting off without decent classic gear, so i'd suggest you put those 13 points in holy, but you really do not need more for 5 mans and heroics.

Focus on +Heal and +mp5 Items and it should all go well.

Put decent enchants on most of the better healitems you get, just to make sure you get the maximum out of them. Its really not that spec-dependant most people think it is. At least it is nothing you can't compensate by some effort.
