Yet another question. 
By the time all the documentation is out, will it be possible for us to create our own classes that vary quite differently from the ones in the core rulebooks? I'm creating my own world and using bits and pieces that I like from a variety of sources that I doubt will be put into this system anytime soon.
I'm wondering if I'll be able to put my own system in there when it's finally completed.
