Firstly, I LOVE the idea of triage healing. I understand why the devs are fawning over the idea. It would be even better if we still had spell ranks, so that players could tweak with efficiency eve more.
but it just is not practical with the player base we're working with. I know that I am capable of doing it, but the average player is not very good at this game and probably won't even understand that the healing model has changed. I think blizzard overestimates how the average player understands changes in the game. anything short of huge obvious raid warnings that say 'stop topping everyone off all the time' means that millions of players will be frustrated by this new model.
