Should GCD Healing also trigger Sage's Kardion effect?

[AmiableApkallu]

SGE should've had a wider selection of offensive spells that apply different effects to your Kardia target.

How is this supposed to work? How is this interesting? That's something I've never understood.

If we ignore latency and FFXIV's netcode, Kardia/Kardion could be a GNB Continuation-style button that procs after Dosis and company. The mechanic is essentially GCD damage + oGCD heal, which is not a new play style. What makes it mildly interesting, I suppose, is that the actual implementation lets you weave in a second oGCD heal of your choosing, despite the 1.5sec cast time on the original GCD.
