I like minions that are various critters and constructs (airship/mammet) but when the minion is a mini person like the fighter and such, or a mini famous person, it kinda breaks the immersion of the game.

Final Fantasy games are about creating worlds, and stories.

Now we have to be super serious and save Eorzea from the Garleans.. .with mini gladiator guy by my side...

It would be like watching The Godfather and in some deep dramatic scene Tom Green walks in and starts humping a sea turtle.
