The healing seems to be in a good place with AST, which can probably be said for all the healers. I think the main points of contention has been less about each healer job's effectiveness in their role and more about how they feel to play, which while subjective and is a matter of taste, has been widely considered such a drastic departure from what was already enjoyed by many players for years to something so unrecognizable that long-time players have been dropping it en masse.

That's not to say that changes shouldn't be made; they should be made to maintain healthy engagement with ALL classes. But what the devs seem to have done is applied a sledgehammer to a doornail, leaving little to no room for compromise between old AST and new AST.

And there was such a large space for compromise too, if they even took the opportunity to explore them. The Minor Arcana conversions for example could have been the guaranteed DPS buff regardless of the card pulled, pleasing the big numbers crowd and the ASTs who wanted to preserve unique effects. Just anything that would indicate more than "We see people complain about not getting one card enough, so despite the fact that that is the point of the card mechanic from the start, we made every card the same without gauging how that would affect the people that have played and enjoyed it like this for years."

Compromise is meant to reconcile opposing sides. Now that they have acknowledged that "some people loved the old system, and some love the new" then maybe they can begin to work on compromise; the problem here is that they've set themselves up for an uphill battle to achieve a happy medium while also saying that they have no interest in even doing so.
