Remove GCD healing from healers. It's actually miserable. No one wants to play healers because people like doing damage. Tanks suffered for years and now that they can self sustain and do decent damage a lot more people are willing to play them. The sad reality is a lot of people just care about feeling useful and seeing big numbers. That's just how mmos work. So let's get them invested in a dying role.

As someone who pretty much only heals or tanks I can safely say if you just made it so healers healed by doing damage rotations more players would be willing to jump in. Do we really want another stack of expansions with a healer drought. You're always waiting on them.
