a way to fix our classes?

[Cairdeas]

But that is the problem no characters are unique because we are all the same with all the same skills that we have cross classed from all the classes. If they physical level system worked properly and I could build my thunder archer great but it doesn't ; ;

So fix those problems, don't try and "break" the current system by removing it.

If you want to be a Thunder Archer then once the job system comes out you should be able to use Black Mage and Archer together to perform that task.
