You'd dump excess stacks within Biolysis windows alone (+ 1 with swiftcast) every 30s.
My point still stands that it would still be Broil + Biolysis spam ad nauseam.
Let me introduce you to GCD heals. 1 GCD, can be used for either DPS or healing. Using a GCD on healing costs DPS.
Aetherflow heals are OGCDs, but they still have an opportunity cost through weaving and ED. Using an AF stack on ED costs DPS.
Having heals with different DPS opportunity costs gives the healing kit some depth. If ED was removed or made to deal no damage, then there would be no point to get rid of excess stacks. All OGCD SCH heals would basically cost the exact same: weaving windows. Wouldn't matter if you used Sacred Soil, Indom, Whispering Dawn or Seraph. Same cost, no depth.
Primary purpose of healing? As long as there is an ED around with some DPS potency on it it has the dual purpose of dealing damage and healing. Making ED do no damage makes it useless; what's the point of burning AF stacks for just more MP?
I cannot stress enough that Aetherflow heals having a solid DPS opportunity cost is a good thing.
Heals should not all be either OGCD with zero DPS cost (save weaving) or GCD.
