I always found what made healer fun in the past was juggling all the small things. No mechanic, rotation, or healing upkeep was super demanding, but making sure they all got done at the same time was what made it fun.

They've continously removed these different things to juggle. There isn't mp management, aggro control, a dps rotation, keeping the tank alive, cards to manage, or pet to control.

While previously we had 6 or 7 balls to juggle, we're now closer to 3.
