Using countries as a draw would be problematic. Many people have their team from another country, like say, they live in USA but have a ..Spanish team. So which country? Also, some countries are disproportionately represented in actual terms, there just aren't a lot of teams from each country... consider how many people in US and how few teams in game American, or for smaller countries which are less than a percent of the overall manager base. So more detailed idea would be interesting, what exactly do you mean?

That being said, it's a suggestion that has come up before, and I am moving this thread to the appropriate sub-forum.
