The healer status quo has always been the same. Heal predictable choreographed damage go right back to one button spam.
This has never really changed despite what people might think with every healer rework every expansion. In fact, I do feel like every healer job has gotten worse over the years.
SCH was really fun, rewarding, individual fairies and had dots to compensate for Broil spam.
AST while becoming a monster in healing, has had its gimmick (cards) hacked away into this mess we have now. It's healing is more than fine and rewards good planning like SCH. It's just that the job is really busy for the wrong reasons. Cards are literally just singe target buffs and seals only matter for you and even then they don't because dps card choice is better.
Nearly everything on AST has a massive disconnect and doesn't flow properly. Divination is just it's own thing not rewarded for rolling seals. Astrodyne is really underwhelming and makes no sense. A selfish buff for a healer that's the least selfish of the healers? ShB wasn't perfect but at least there was a system. Draw, cast, seal alignment, Divination, repeat with filler cards being Lord or Lady. AST is just a giant timer at this point.
WHM is the only job that changed for the better. Because it had nowhere but up to go. Aero 3 removal is still painful.
They will inevitable screw up SGE and then the other healers some more. The dev team has shown time and time again, that they desperately need a seperate team to balance jobs. It's clear they are out of creative power which has lead to some horrible and dumb choices. Kaiten removal, NIN rework, all of MNK.
