FFXIV really had a skill bloat problem during HW. Then they trimmed a bunch of stuff with Stormblood which was alot of early mid lvl skills at the time that they say were rarely used. I think that was around the time cross job skills got changed as well from being 5 blank slots the player could assign certain skills learned from other jobs to just being a generic unlock if a job of the class has reached lvl threshold but only jobs of that class get it.
