I think the problem with the campaign nerf is it was needed but it was late and for some people this way of XPing became a staple for them. I don't have a problem with it, but I can see why others do. They should have fixed this sooner.
I'd be surprised if SE added anymore jobs. They pretty much covered all the basics and they as far as the world of Vana'diel, they've pretty much covered everything except East Aht Urghan, and the Mithra motherland.
