As I level some classes and make goals for myself, I sometimes think back to the notion that classes were designed to hold twice as many cross-class skills as jobs. I often wondered if I somehow constructed a build out of ten cross-class skills and an un-upgraded class, would I be laughed out of endgame?

I hear a lot of the endgame gear is job specific. Is it all decent endgame gear?

So is the "feature" that classes can assign twice as many cross-class abilities useful at any time? Can it be made useful for endgame? Thoughts?
