One of the big changes for druids is that some of the changes means that depending on your healing style and also your assignments your optimum spec could vary a fair bit.

For the first time since hitting 80 I will be running with 2 resto specs.

Spec 1
I think this will be my raid healing type spec. I have dropped Natures Grace and put it into Revitalize just for the mana/rage return etc.

Spec 2
Tank heals. Pretty much as my spec is now.
