Back to the actual thread--sorry for my tangent...

I'd rather not use any of the original systems, but I can't deny that they'd be pretty "FF" to use, and would enjoy seeing the customization. Honestly though, I don't think any of it's going to make much difference without more depth being added to the classes themselves, which won't really be doable until more depth is given to the combat system as a whole, and the method of giving and defining abilities has been restructured.
