I hadn't really kept up on news on the game for the last five months or so I wasn't playing. When I left I think it was just recently announced that they'd be adding classic FF jobs somehow and I was interested to see what they did with them, and how they would resolve things like giving white mage and black mage spells to the same class.

Now from reading this thread and a couple lines given in more recent interviews/magazines it seems all it is is a little toggle you throw on to make your class more specialized so it can be more useful in a party. And I have to say that sucks, a lot.
