Square take advantage of your amazing world you created for endgame!

Or do it like in FFXI when you cap you get Merit points, for every level you get a bonus one point to add to any status. Not only make it a great end game, but encourage level 50 to keep going. Right now, once you Cap you basically done and you will never revisited old Dungeon or Fates anymore.

I slightly disagree with this, on the basis that you can still run FATEs for company seals and a bit of pocket change, and there are FATEs that drop items, like minions. Plus that upcoming FATE that will give the FFXIII gear.
