While I do not agree that FFXIII was autopilot, XIII-2 definitely was, because it was easy as hell, even with DLC bosses. The fact that there are less abilities than FFXIII doesn't help, it means that there are less things to choice, the only time in which is not worth doing auto battle is with the SAB role. XIII was a lot harder, and I think that using auto battle here doesn't mean you can't beat anything/anyone, it just takes twice as long [?].
There are also other FF games that are more autopilot than XIII. XII is the major culprit, that game can play by itself, no skills involved.
XV looks like a game where your skill is very determinant, at least against powerful enemies/bosses.
In Type-0 battle system (which I view as a downgraded FFXV battle system) you could beat enemies 30+ levels above you without any problems by using the right strategy, but maybe it's because some abilities/characters are broken as hell (Rem, I'm looking at you lol).
Speaking of broken and unbalanced stuff, I hope FFXV doesn't have any xD
