New crafting job that creates "enchantment" materia for a new "optional" slot on all gear or some gear?

Enchanter's can craft materia plus items to create special materia with "dual stats". Think combining Crit with Determination. Or, effects.

Maybe, alittle less contention, glamours. Creates simple effect like weapon and armor glow's.

Alittle more, utility. Increasing specific enchants to boose timers on GCD's?
