I'm sure it'll be the level cap to many players who are waiting for the promised 8.0 to deliver as Mr. Yoshida and Kiyru (The CEO of Square Enix) are heavily implying to the shareholders and customers both.
If it fails to deliver, then the current level cap will be the last for many.





More directly: Personally I'd like to stop leveling upward and instead keep the horizontal progression if we must and find ways to gain spells or earn rotations through another means.
