I might have missed the mark on player complaints, I concede.
But let's talk about how the devs themselves can't seem to create high end content without constantly dumbing down the jobs. That's the real crux of the problem. While 1 Ultimate did indeed exist in Stormblood, that's an anomaly, and it was just 1, as we saw. Square enix gets very sensitive when people says "job balance is so bad, I can't clear this on mch because Bard's unique skills are needed."

Yoship himself told us to play Ultimates if we want challenging content as healers. That's the biggest clue why the jobs are so dumbed down; they're designed around High end duties, most notably Ultimates. Why account for 20 something jobs when we can design 4 tanks to all be the same way? etc
