I had actually avoided Focus/Rage as a matter of personal pride, I found it boring/simple spec to play, and while more productive from a damage standpoint, I thought my heals cancelled it out. I.E. I was ok with doing 100k less damage, if I also was doing 100k heals on top of my damage.
But now? Focus here I come...
