I'm just going to quote myself from a conversation I had with some friends, it sums up my issue with healers.

"if you described 14's healers to someone who knew nothing about 14 "Basically you deal as much damage as you can but when needed you heal but only when you really have to, you want to heal as little as possible and deal as much damage as you can" They'd likely think you're some kind of attacking support, not a primary healer."

I play a healer to heal, but in 14 I'm praised for focusing as little on that as possible.
