I got two points I wanna suggest:

1. Magic interruption.:
We all know that if an enemy hits you while you're casting, you'll get interrupted and gonna have to mage the command again and hope it don't get interuppted again.
Something else you can do is instead of letting a spell be interrupted, is letting the casting go back a few % or even start from the beginning. This will let the same command go of right away but still being interrupted in another way.

2. City and camp transportation.
I know we'll soon get rental and personal chocobos, and also airships. That's awesome, but there is still one thing I miss to not make the travel go faster or easier, just more relaxed.
Why not being able to rent a chocobo that will run from a city/camp to another city/camp automaticly?
You can only go from a city or camp, to another city or camp. That way normal rental and owned chocobos still will have their use since you can't go anywhere more specific then camp/cities with these chocobos. That way airships will still be used since it takes quite a while to run even by chocobo Ul'da > Gridania, the other way around, and in the future, travels to Ishgard.
And even the same for teleport since using anima to another city or camp go in an instant when chocobos even here takes a while to camp, specially camps far away, like Ul'da/Gridania to raptor-camp.
Perfect when you're low on anima or need your anima at a later moment.
