How would you feel about end-game gear only being useful for 3 months?

That is some good insight. I hadn't thought of that. I'm still getting used to the implications and dynamics of the Armory, soon-to-be Jobs system.

Actually the Armoury System isn't going anywhere. Classes will remain intact. In fact new ones will be added. People will still be able to mix and match skills almost 100% freely as they do now. The Job System is a separate add-on to the Armoury System.

Essentially one can say that the Job System is to the Armoury System what Materia craft is to the crafting system.
