I think making carby out, and granting access to the two carby skills, would help some in things to do department (rather than them locking off, if they're locked off when carby is not out- at that point might as well just have them morphing skills). Though if we connect it to aetherflow wouldn't that mess with radiant aegis? I suppose you might consider something like 1 radiant aegis is free with cooldown but when you earn aetherflow you can cast it one more time (consuming the charge of course, though people might argue on if free version should have priority or not- like if you want to be forced to use aetherflow to use the skill, leaving the cooldown variant alone or if the cooldown variant takes priority even if you had aetherflow active).
I'd love to see physick gain that sort of interaction though, aetherflow physick doing something worthwhile. Maybe physick is changed to have a higher mp cost (or cooldown), but scales with INT (at least as far as I remember it's still MND- I know when I use it at current level it's a terrible terrible skill wasting my bar space on most days lol). Alternatively than higher mp cost initially might be like each consecutive cast doubles the mp cost. Then when you use it with aetherflow it causes carby (who doesn't vanish anymore), also cast a spell- perhaps an equally strong shield onto the target that if broken deals damage a bit like TBN on DRK allowing for skilled use to mitigate cost (Although maybe still a little bit of a loss compared to DRK, shield because carby in other FF is known for using reflect).
Although personally I still kind of want the fester and painflare to mix with aetherflow stacks for unique primal effects. Like Gaol for fester (single target strong CC + fester damage), Tumult for painflare (echo's aoe damage after your following actions up to X). Although that perhaps could be some other skill, so there are even more :D (though I do encourage continued use of morphing skills, I quite like that).
I know it's not the coolest use of pets, and maybe SE is being strict on this because they want it to be different (like Dragoon and animation lock lol), but... I feel like it would be better in some cases to have the damage / effect come from you using the ability and "try" to get the pet to animate on time but if it doesn't then "woops". One thought to make that feel better though was to make it so when you use abilities on things that aren't out, then trigger the effect independent of the pet (but do your best to line them up as often as possible, if the ahk morn drops before bahamut is fully out then.. not terrible), THEN when pets are out and you use things that rely on them.. rather than cause that unit specifically to respond to the animation use the ninja ghost like effect (when they duplicate their attacks) to animate the casting on top of the primal itself. Either way stuff is getting done on a consistent schedule.
