Then the argument at the moment is currently invalid. We don't 'know' anything about the proposed system... only that it's a Job system to work alongside the Armory system. We can't say what is good or bad for something that has no basis.

Which is exactly why this whole thread has been about what we 'want' to see: freedom of character development.

There's no point in worrying about how to balance such a system, that's what the Devs are around for, and what it is their job to do. They won't create something they don't believe they have any chance of balancing, or which doesn't begin at least remotely balanced, no matter how much we argue for it. Yet if we don't argue for it, there's less chance that they'll implement anything even remotely similar... no matter how much it may have been used in Final Fantasy games to date.

The FF team is not the same as it used to be, and the newer installments to the series reflect that clearly; we can't expect anything from the past from them.

If we want it, we must make it clear.
