I took a long break from WoW, and recently resurffaced and joined a casual raiding guild to get my feet wet again. My question is, I do a lot of raid healing in my 10 man team and was wondering what is more important? Haste or Mastery? I've done a ton of research on my own and my conclusion is because it is 10 man the decision is ultimately mine? Does anyone agree or disagree with my statement?
