Danoob:
I'd like to contest you on two points.
1) Your mod rank now matters. Absolutely not. In every wushu mod out there, a guy named "Pr3yer", a stiff unimpressive player holds near rank 1. In brushu, it's by a gigantic amount. Meanwhile there are guys who are in triple digits that outclass him in every way.
2) The better player having a "good chance" to come out on top isn't apparent enough for ELO to work. There have been times where I won 4 games in a row in wushu, lose to someone, and my ranking is lower than what it started out. So even if there's a pretty decent advantage, it's not good ENOUGH.
