[Kallera]

In FFXI when they did anything that would change how much XP you had tnl, or added levels. If you were Above what the next TNL would be.

IE

Before the change your XP is

40,000/45,000

And after the change to get to the next level you only need 35,000. Then your XP will be.

34,999/35,000 And anything over that would be lost.

There was also some reasoning behind have xp gains after lvl 75/99 in FFXI. the death system took away exp, so it provided a buffer for players to remain at their level.

Since that's not present in ffxiv, it isn't needed per se.
