Thank you. I'm hoping Square tries something like this with a mainline numbered FF game. But not with XV, though. I'd like an updated version of FFX's battle system to be in that.
How could you possibly update it? The only thing I can think of is making the character progression, skills stats and such more complex. The actual battle system should stay unchanged.
I'd say it needs to be way less tedious for the end game stuff(Arena Dark Aeons and Penance), when the enemies HP start reaching the high hundred thousands and Millions it's horrible especially the Monster Arena things that drop the stat node spheres. Same with the Sphere Grid which gets just as boring at the same point.
