I don't get it. On one side of opinion here, only the 6 best players from a given country, chosen by what will surely be a popularity contest are going to play. On the other side, an uncertain amount of teams will play. It would seem to me that it would be best if everybody who signs up can play. If you look at the gridstats map of MB53 players http://gridstats.com/mb53s-mega-fortress-pro/map
, you will see that the United States of America has 357 players, Germany has 116 players, then the counts per country go down to 26 for France and less for other countries. To me, it would seem that Germany can probably field at least 2 teams, and the USA 3 teams, all to be based on sign-ups, of course. I don't understand why you would limit the number of teams in countries with lots of sign-ups to be significantly less than the number of players. To me, all this says is that if I sign up as a player from the USA, I have a lot less chance of playing than say one from the Russian Federation or Serbia. Perhaps Luck is the smart one to sign up as a Russian, since the likelihood is that he will actually play is much greater than if he were to sign up as a player from the USA.
Quite frankly, the way this is headed, if I were going to sign up, I would sign up as a Serbian or Russian. At least then, I would get to play. Of course, the net effect of this is probably going to be that even if you do only allow 1 USA team, the other USA players will just play for other countries that have few if any players. So, you end up with multiple USA teams anyways.
