they never acutually said no cross-class skills can be used on jobs. they stated they would limit. it may mean you can use less skills on your job due to the job skills taking 5 slots of your 10 or it could mean the selection on jobs is farther limited. they may make it to where you can't cross any, but i doubt that. the reason being is that unless they allow some i still think the classes would be better for a party besides adding a bard.
