while being able to change up your subjob to fit different needs was pretty cool in ffxi

ffxiv went from having subjob-esque cross class skills to removing that and giving all classes a "pick 5 of these 10 to be usable" and now even farther away from subjob with "well all 10 are now usable so whatever, enjoy the loss of unique class animations for nothing"

basically 14 is stepping farther and farther away from anything resembling subjobs, going back that way now would probably require more effort than they'd want to commit while also messing up anything they happened to balance around class skills replacing cross-class skills
