Why are there no multi-hit skills on Sage?

[Absurdity]

Broader question, though: Is it feel better/necessary for Kardia's interactions to exploit multi-hits specifically, or just that it should be able to exploit variances in its triggering GCDs?

I feel like literally doubling/tripling/quadrupling its value via multi-hits would mean, in accordant balance, that the single-hit version would hardly be noticeable, so I'm a little worried about attempting to give it such a range.

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.
