Let's not pretend healers haven't gotten screwed over throughout the expansion cycles. Scholar got its DPS nerfed hard at the start of Shadowbringers, and every patch they make some kind of change that kills part of the Astros before to make room for the upcoming patch: removing the time elements, changing the cards, etc.

I really can't say I'm surprised since they originally wanted it to be a third healer that could go between the two, but so that things could be perfectly balanced (as all things should be), either they'd have to introduce another healer that can straddle the line or they were going to screw over Astrologians.

Pattern recognition wins out.
