Hey Hanzo, you made my set remember me? Anyway, I agree with you totally that join date and fights played doesn't mean you have a good suggestion..... BUT I do think it gives me a shit load of insight into what would be fun in the game. I also agree it could be a balancing nightmare but. I still think it's worth testing out in any case.

I'd be interested to hear what people with authority and ability had to say about the idea, which I'm positive they've probably thought about to some degree.
