There is absolutely no reason for 2015 and Beyond FF games to be stuck in the ATB combat style.
Don't like that? Go play the old FF games. That kind of combat was perfect for the late 80s and 90s because systems weren't really powerful. Now it's 2015 and we have nothing BUT options and no limits holding creativity back. And there are still people that complain about FF straying away from turn base combat. Like... seriously?
