I'm not exactly in charge of TDR's rank system, but I know we're currently looking into changing it or removing it for exactly this purpose. Our current rank system is flawed as it is based around symmetric games such as HL2 DM, as you've said, so don't hinder this idea because of a system we have in place. We want to change it as much as you do.
In any case, isn't this the wrong forum? Shouldn't this be in I&S? xD
