Because I want to use Clemancy in current ex trials and savage raids, I want to use it in expert roulettes and trial roulettes and also older synced content. Using it only sometimes in PotD or HoH or Bozja is underwhelming at best, or only using it as emergencies during failed runs just doesn't out weigh when I could be using it more often instead. Having both current Clemancy and an OGCD heal probably won't ever happen, and even if it did, they'd only add it at a super late level which isn't ideal. I want it specifically to be Clemancy because Clemancy is unlocked in early HW, therefore I could use this OGCD heal earlier than only in the next expansion going forward.
