Mostly I wanted to ask why you would be looking to skip Improved Healing Wave? The only alternative is Totemic Focus, which as far as I can tell has only dropped in value since 3.0 - is there a good number of mobile fights coming in Wrath, am I missing something, or is it just a case of min-maxing Totemic Focus' straight mp5/talent point against Improved Healing Wave's "improving a spell I don't use = 0/talent point" value?
More the latter I'm afraid, and thats mostly due to the fact I'm not particularly familiar with totem costs. The general idea I was working from was "why buff an ability I will not be using?"
