Quit avoiding the question and answer it with a reason. Why do YOU feel the need Classic needs to make stats private? It doesn't matter if the other servers have it, do you see unbalanced weaponry in Classic? Not at all. Making them private will only lead to what I and some here stated.
Side-note:
Classic will be the only server that doesn't produce the same ideas. Era, Ol'West, and Zone are literally the same mechanics with different themes (Modern, Space, Wild West).
