Honestly it's time for common sense. They've had amazing landscapes that people loved and these few artists who designed them. This has been the core of FF titles for over a decade. They tried to switch it up by putting new people in charge.
Any sane person would fix the thing that didn't turn out well by using those artists that have been proven they can do it not only with good quality but exceptional awe-inspiring originality.
It's better to use people who can do it than just go tell your AD "can you develop some imagination please?"
