Concise description:
New points system which includes a factor of how much variation there is in a player's games.
Specifics/Details:
If a player plays a wide variety of maps and settings this should be reflected in their score, as opposed to players who only choose the same type of game repeatedly. A variation factor, that could be multiplied by the score, which would increase as the amount of different settings a player succeeds in.
How this will benefit the site and/or other comments:
It would stifle players who create 20 games with the same settings on the same map every week, playing against those who are unfamiliar with their tactics. This is a cheap way to gain easy points. It makes the score and rank unrepresentative of the best players.
It would promote the use of lesser used maps.
Most importantly, it would find the true Conqueror.
