Stray thought I had. Why is it the only companion pet we get is our combat chocobo? I mean, sure, there's the old egi argument of "it fills all the roles, what more do you need?" But seems like there's a lot more devs could do with that system providing more options with different styles.

Tangential thought that could probably be its entire own thread: I get the impression that this is among many early features that were implemented, with plenty of room to expand upon, but have largely been abandoned as the game moves forward (such as the Hunting Log).
