Scholar really doesn't play that much differently , it's mainly been reeled-in from it's overpowered MP management, and it's free healing when it was always clearly #1 in that area among all healers since the job ever came out. That was also why minimum PIE builds were always considered best-in-slot. Making a relic? Absolutely no PIE in that weapon. The job could get away with practically almost no gear having PIE in Creator Savage, and still put up powerful HPS and DPS provided your raid parties were not error-prone. So even not being the slightest bit optimal, you'd get away with it or just add PIE somewhere for traps/messy parties. Aetherflow going from 20% to 10% now makes a little more aware of using the correct skills for the situation. But like some posters have also eluded to, you only need enough MP to "always be casting". I've had to train my bards previously that I didn't need mana song even when it looked like I'm super low of MP.
Practically going back to ARR it was Embrace/Whispering Dawn doing all the dungeon healing. Double/triple pulling a heavy dungeon pack in 4.0 in a 310 sync dungeon you'll have to play it using all your skills, but they gave us Fey Union which is really super-sayan for even the heaviest dungeon pulls and constant tank raid damage in the game. Which you didn't mention, and requires only aggressive Aetherflow build-up. It's once again, free. Oh you can pop Rouse+Whispering Dawn to get another tank regen before you pop Miss Super Sayan tether. That's two powerful regens, and now you got more Aetherflow in-case they dip into emergency range while you DPS down the trash. Easy game.
There are a few threads in this forum to explain and help force the fairy to stop what she is doing to do things like Whispering Dawn. Even Sustain had a purpose because she would immediately stop healing someone to heal herself. Most of the time that wasn't necessary as a Scholar because the most she probably had was a tank cleave and she lived through it without any more damage coming. But to say clunky fairy is about akin to saying Benediction going off on a dead player. It hasn't stopped anyone from playing pet jobs.
