I'd play in the league... and here are my opinions on the matter:
- Only 1 vs 1 games.
- Only track wins, losses, and win/loss ratio
- Only count the first game you play against someone for total Wins and Losses (this would ensure that people keep playing against new players)
- Use seasons. Declare two winners at the end of the season: Most Wins and Best Win/Loss Ratio. If it isn't the same person, then those two could duke it out for the Supreme Crown Of Devastation and Destruction. (and obviously, you would need to have a certain number of games played before you can qualify for the best Win/Loss title).

I think that a ranking system only works well when a lot of games are played. Since SE4 can be so time consuming, trying to squeeze in a valid ranking system will likely only lead to frustration.
