Matsui you seem like a forward thinking guy, it's time to look at uncapping merit categories especially the group 1 & 2.

In its current state there is no way this would break the balance of FFXI. Allowing NIN to cap all elemental :san spells to 5/5 or WAR to lower his ability recasts by a total of 50, seconds simply can not be that detrimental to the overall experience of the game.
