^Poker face. Lady Scourgaga approved. True story.
In all seriousness, I think that renaming the magic in the game is one of those super easy little things that SE can do to make 14 feel more like a Final Fantasy game. For the people who don't know FF games of the past, it wouldn't matter. For those of us that do, its a little nod to what we know. Sure it doesn't mean too much in and of itself, but a lot of little changes like that can add up fast to make the game "Feel" better.
