I think people really underestimate how long it takes them to make changes. They just don't change things willy-nilly. The plan was that in 7.0 they change up encounter design in response to feedback, which Yoshida has said we will really only start to see now and then in 8.0 job changes are coming.

Personally I'm afraid because I like how White Mage is right now and I'm terrified they are going to listen to feedback and add some kind of rotation to White Mage that I won't like. But we all have to wait and see.
