I don't see mixing and matching jobs with classes working out.

Assuming each class has two jobs associated with it, we have 14 combinations. If we allow mix-and match, that's potentially 7 classes x 14 jobs = 98 combinations. Far too complex a system to balance.

As much as I would love to play a paladin with an ax, I'd prefer to see the more limited version succeed rather than a repetition of the problems we originally had with the great-on-paper original armoury system.
