The better man? There is no such thing [base class]

[Rizban]

Isn't there already a cap on number of natural attacks in 3.5?

Also, why not allow the higher number of natural attacks but make them exponentially unlikely to hit?

I don't think so.

That's rewriting the core mechanic for natural attacks. It's much easier for people using the class to just use the existing rules for them than it is to try to write and learn all new rules.
