I haven't played JRPGs in a decade and a half, so I keep forgetting that there's playable characters who have only a tangential connection to the story with no good reason to be part of your main team. See: Irvine in FFVIII. Why does he exist.
My least popular gaming opinion is that I did not care for FFVI, and I think that was part of it? I am willing to accept that I played it 20 years ago and my memories of it are colored by being an obnoxious teenager who went into every game expecting it to be stupid, but VI never won me over. By the time it got around to characters like Relm and Umaro I was just done with it?
Maybe being away from the genre for so long has changed my opinion on this a lot, but I feel like these games could benefit from leaner casts that I can have a stronger emotion connection with, rather than a sprawling but diverse cast of hangers-on?
