I agree with Alexia Kidd and EdenArchangel, get rid of the 1 weapon = 1 class system, even if you keep the current classes in the game. I wouldn't mind them being reworked into the traditional FF jobs too.

If you really must, you can keep the "open" system with skills, allowing us to mix and match as we level the classes/job. But to be 50 GLA to unlock an all ready 50 PLD is a big turn off. Now if it unlocked a level 1 job called Paladin with it's own personality, then I'm all for it.
