Let,s say the make a way to breed or have more than one choco. That would awesome. Though you maybe only able to call one choco at a time. We may see some changes when they release an expansion and maybe they can make new jobs. So that we can further train or allow more ranks like up to 20. I think being able to form your own party is nice with a choco. As for the choco i have all 3 job abilities unlocked though limited for each. For now i appreciate we can use chocos to aid us in fight.
