Personally I see less of an issue in the healing amounts that are present in the game and more in the ease of access to their best use case scenarios is, rarely will you ever find anyone complaining about the likes of Healing Discharge, Healing Cantus or Gentle Garden given their respective ranges. But you'll always find those people complaining about massive AoE healing that really doesn't ever fall off in usage, such as Second Set, Malmelo, Phoenix and sometimes even Graft when paired with Mass + Rescue.
It might be more prudent to target the access to healing than to target the healing amounts themselves cause I quite genuinely think in most cases the amount of healing that can get done is quite manageable (Except maybe Elves, you'll finally get me to admit that), maybe hit Priest's +50% healing passive to +25% instead if numbers are still an issue.
