I have to agree with answa and theve. We already have "masterclasses", only in FF they are called jobs. We have an armory system. I find the armory system appealing. I like the idea that now that I have invested my time leveling CNJ, that I get the benefit of using the transferable abilities/spells that I earned with my time. I enjoy having base classes, and the jobs seem to be headed in the right direction.

Sorry, but I just disagree with the OP. As the OP mentioned making the jobs an advanced version of the classes, well, I see that happening soon enough. Once more jobs are added to the point in which we have 2+ jobs per class, I am certain 1 will be an extension of the class. The other will perhaps be more like bards relationship is to archer.
