I know that the main focus at the moment is to get every summon in FF history to battle and also CT will be getting turns at regular intervals.

What would be cool to see (in addition to the standard patch stuff) is dungeons designed so that players need to use their chocobos in there and would be ideal to get those hard to reach companion levels.

This shouldn't be too difficult to do as you could cap the number of players to VERY low numbers so the battles should be pretty easy to adjust.

I love the companion system but like many I feel like the game currently doesn't have any content that let's you unleash their potential.

Maybe even chocobo Limit Breaks?
