Astrologian.

Taking the core aspects of 2 different jobs and throwing them together into one job, and then adding a bunch of extra utility for good measure, is downright stupid.

Astrologian has single handedly warped healer balance ever since it's release purely because it's a hybrid. Healers will never be balanced while it exists in it's current form, because the nature of hybrids is that they're either too good or bad, never in between. Not only that but it severely limits future healer designs, they will have to possess either some form of regens or shields to compete, regardless of their personal gimmick.

Remove the sects, and rework the job to be more about the cards/buff manipulation/instant casts, then it'll actually feel unique enough to stand on its own instead of being a "WHM/SCH with cards". PvP Astrologian is amazing to play, and I hope they push the PvE side to match that.
