I always felt the best way to do it, while keeping the spirit of the system, is if they incorporated an ability equip system like IX's. Where your characters level determines how many Licenses they could equip (including augments) this would create better structure without frustrating the player cause they know they could only get a certain amount of augments or abilities. Say at Level 50, Basch could equip 255 points worth of License and thus each equipment and augment or spell cost a certain amount of points. I know it sounds confusing but it seemed like the best solution I could come up with to make the game accessible to both hardcore and casual fans.
