Astro is actually in the best place it's been since 3.5, it's almost in that OP category again. Savage is the barometer YoshiP sets for healer parity, not dungeon content. If anything they got the healer checks in Eden's Promise Savage better tuned this go-around. Plus they went back to the torture us at the end-cap fight, keep healing or risk losing all together.

Healer burnout has been happening for awhile, same jobs for five years with little changes. Usually you are looking for a non-WHM healer as your last raid group spot, or waiting in PF for something. In a sense this entire 5.x series has been trying not to make one healer fall behind. If anything I'll probably end up saying 5.x was probably the worst expansion in the history of XIV for healers. Nothing good in return, except trying to keep the status quo.
