As this is a Final Fantasy game, or so they keep claiming, they should be taking pages from other Final Fantasies, preferably not named XVI, if they ever do any kind of overhaul for combat, which they never will.

Role actions really should have been exclusively situational actions that you assign and replace based on what kind of encounters are coming, which would not be dissimilar to how pretty much every non CBU3 Final Fantasy handles combat loadouts. That would not only add some small degree of loadout planning but also discourage the exact same rotation being applicable to just any fight.

Not that it matters. They're never going to do anything of the sort in XIV. They can't even design healers right.
