So you heal for more during your one-minutes. So do you now from auto-crit heals. So does Paladin from Requiescat.

So it has a potential decision to be made between maxing damage and increasing healing. So does Clemency.

I don't see an issue with the sync/dynamics or decision making tbh.

If you do, though, then there's still diminishing healing returns after the 1st enemy struck per action. Without that, instead following your original suggestion of 130np, there's basically no AoE scaling until 4+ targets.
