RPG, many characters join, but you just use the first few the whole time

I deliberately try to rotate in characters these days, though sometimes there are a few characters I just don't bother with. I don't mind if it makes the game more challenging that way, as it's more interesting at least.

Trails is a good example where I really try to rotate in everyone. Although there's a couple of games there that have some characters join very late that I didn't bother with.
