From what I understand, new jobs will be implemented. Black Mage, white Mage, warrior, dragon knight, monk, bard and paladin.
So does that mean that a paladin will simply be an advanced gladiator, that is, gladiator with a higher class, or are jobs entirely different? So does that mean that jobs can use whatever weapon they want, like ffxi, or will jobs have to use the corresponding weapon. I remember that in ffxi a warrior can even use a katana but it won't be effective.

I just hope someone here can be kind enough to clarify this and tell me if there are any differences between classes and jobs.
