Jobs are going to be specializations (think any other MMO) that takes your base class and makes it more adept at a particular role in a group. The Job system is not meant to replace the Armory system. It's meant to augment it.

I just wish they would do more than 1 Job per class. It would make things like CON -> BLM or CON -> WHM make much more sense.
