If Fey Blessing had evolved to be 'pulses AOE healing at cost of gauge, as an AOE version of Union' instead of 'scuffed Indom', it'd probably feel a bit less tacked on. Still not ideal, but at least it'd be considered a 'good part of the SCH kit'

Maybe they'll make it like Oath, where fairy heals generate 5 gauge per heal and 'currently aetherflow spenders' cost say, 25. And ED stays as the lone AF spender so there's no conflict of 'damage vs healing' for AF stacks anymore. And very few people would complain about 'oh but what do I do when I'm capped on fairy gauge' because look how often we're capped on Sheltron Gauge or Fey Gauge atm. I feel like I'm always up at 100/100 on the Fairy Gatorade Bar because the tanks heal themselves so much now it's hard to find a good spot to use the damn thing sometimes
