That whole argument tangent was ridiculous. I read the whole thing. Loved it.
Some of the arguments were a little illogical or flawed at times, but that didn't take away from the passion. The passion is what counts.
I can see the frustration of wanting a prestige class that doesn't quite match up with your exact build or character vision. (Having character vision is, in fact, meta-gaming)
Unfortunately, that's the way it works in this system. It makes sense within the confines of the D&D rule-set.
I think an interesting alternative would be having base classes and prestige classes with variable pre-requisites. Like instead of 8 points in sneak/hide/listen/wilderness survival... just dictate 32 points spread between them.
Alternately, you could do a more open system using a generic prestige class, and have your skills, attributes and existing feats make certain class abilities available at certain levels of experience. Basically it'd be a more malleable feat system that would govern class progression past a certain point. Like Oblivion's build your own class.
