Speaking of FFT style unloocks, maybe you should have other classes ranked up. For example:

Paladin/Dark Knight
R30 Gladiator
R10 Conjurer
R10 Thaumaturge

Warrior
R30 Marauder
R10 Gladiator

Dragoon
R30 Lancer
R10 Gladiator

White/Black Mage
R30 Conjurer
R15 Thaumature

Samurai
R30 Lancer
R10 Lancer

Think you get what I"m going at.
