I am kind of happy, I don't want to level everything up separately. With all of the current classes in the game, and thinking of the potential classes in the game, to have to level them up in addition to jobs, completely separately would be an enormous time sink. If there was more variation in the areas/styles you could level up then I would feel a little better if I had to level them all up one by one, but that is not the case.

If classes had to be leveled up in addition to jobs, I would want to level them up at the same time at least. Kind of like how you level up and rank up at the same time (or gain skill and experience points at the same time). I would have wanted it so if I was a White Mage and had a Conjurer weapon equiped, I would skill/rank/level up on them both at the same time.

This may make some players unhappy, but every decision SE will ever make will impress some and disappoint others. I am personally happy with this, happy that at least I don't have to level everything one by one in the same area over and over and over and over and over and over and over and over and over and over. And over. I already have to do that with Classes.
