I'm not confusing anything, Cairdeas.

Jobs are simply battle roles that the classes are being given. That's it.

At the end of the day, our combat system is still the armory system, which has not changed from day one, and classes being tied to specific weapons are still the crux of it.

You are arguing that you don't like the armory system. That's fair enough. I'm not so sure I even like it. I would have preferred this game to have started from the beginning with a job system like other FFs.

However, I am refuting your notion that THF is impossible because they are making jobs tied to specific classes, which are in turn tied to specific weapons. THF is more than possible in the current system. It will just require that THF either be an added job to GLA to use the current GLA weapons, or they can add another class down the line that uses a different weapon (Because remember, the name of the weapon doesn't really matter as long as it is different) which could then evolve into thief.

Here's another scenario. Imagine that SE decides Thief is going to be a class itself and then it evolves into a job called treasure hunter. The possibilities only go as far as SE has the ability to imagine them.
