Why are there no multi-hit skills on Sage?

[Shurrikhan]

I would replace already existing Sage oGCDs with those multi-hit abilities, so the normal single-hit version would still be noticeable as your passive healing (like Eos) since all of your big Kardia heals are still restricted by cooldowns.

I think the plan isn't really to just staple high potency Kardia healing on top of the already strong oGCD heals that Sage has, but replace the fire and forget abilities with something that interacts with your core job mechanic.

I mean, feel free to bind/siphon additional healing potency-per-minute specifically to attacks as you wish, but that seems a separate issue.

Which seems like the better fit for what should heal more on Sage: Greater total damage in the given spell, or solely the numbers of hits it has? Effects being arbitrary, should the big lazer animation Pnuema heal for less than a bunch of wispy little muted shots via, say, Smínos Melissón ("swarm of bees")?

Is there something you specifically want from a dichotomy where some skills may deal more damage (via fewer hits) but others heal for more (via a lower total damage but more hits)? EDIT: And does that seem like a healing/damage priority lever that you want to create specifically in that way?
