Well, I guess that's one way to deal with server congestion.

As usual, I will reserve judgement until I can get my hands on the actual job but my healer journey through the game goes something like this:

HW - Scholar is my preferred healer because I enjoyed the damage mitigation over pure healing the class offered. Pretty much ignored pet because it was there to heal me. Adlo was my base heal (didn't even have physick on my bar).

SB - Higher mp costs made it so I can't run that build, also confusing stuff was added to the pet (which I still ignored) but after two expansions I finally memorized AST cards and liked the changed to the draw system (plus AST still has shields like SCH so..yay) so I switched to using primarily AST for this expac.

ShB - Wow. Have to memorize cards again? Ugh. Scholar has even more confusing pet stuff? Looks like you're it, WHM. Lillies are awesome! *Spams overheals*

From this journey you can probably tell that I'm not a healer main (BLM main, actually) but I'm sure for actual healer mains, this is a more profound struggle.

But to address the bigger issue here, its obvious that DoT is becoming window dressing and not the focal part of any one job. Any changes to the base class (ACN) pretty much have to be reflected by both SCH and SMN and the weeping over SMN changes is loud indeed. I'm actually excited by them but others... Not so much.

This happens every expac. People see changes to their job and are immediately incensed but somehow during the next expac people either get over it, switch to a new role/job/class or quit. And SE has already guaranteed that for every healer who quits, someone playing Sage will be there to fill the gap. Perhaps not as good as a vet healer but yes.
