Why are there no multi-hit skills on Sage?

I certainly wouldn't mind as that would require some planning instead of just "press button, make green bar go up".

The only problem I can see is that if it’s a DPS loss it goes down the route of ShB lilies, if it’s neutral it just ends up like pneuma where it’s functionally an oGCD or if it’s a gain then the heal stops being important
