One of the bigger things I can think to change is the Chocobo companion functionality. As if stands now the whole system is just too clunky. In this game we are constantly mounting and dismounting, going from one location to the next. Having to repeatedly push 3 separate buttons each time you dismount , summon your chocobo for a fight, then dismiss and press mount again, is just too much of a hassle for not only myself but most folks as well. Which is why most ppl I see don't even bother to use this feature. Take some hints from Star Wars: The Old Republic. The companion in that game was able to be auto summoned / dismissed based on party size. Also simply hitting the mount button should automatically dismiss your companion/ chocobo and cause your char to then mount him as normal.
