Ehhhn. Ninja also comes from Thief in the very original Final Fantasy, but Knight (essentially Paladin) comes from Warrior in that too. I don't think we should make a classic Job into a Class just because it synchs up with how Jobs worked in previous games.
In FFXIV, a classic Job is a Job you get from a Soul Crystal being equipped with the right Class. Classes are something more basic, about the weapon or tool you hold in your hand, and never a (deliberate) reference to past series games.
