I wouldn't mind a simulated WC completely under the control of Nordeus. Take a server and separate the WC's by level. So I'm level 6 and American. They would take the best players from every level 6 American on my server and form a team. And since we all have players of various nationalities, and some are outrageous (I've got Bahamas, Somalia, American Samoa, Mongolia, etc.), the player's nationality could be thrown out the window in favor of using the managers nationality.
An AI would be the manager but games could be posted in Friend's Matches so we could attend the games and give them support. The game be would simulated just like the rest. If you're player is selected to the WC roster, he gets the benefit of the added experience. Just an added bonus for your player, a little something to cheer for, and a little friendly competition without any risk to us or our players.
And maybe the only reward is a trophy in your case if your player was on the team. Nothing too serious.
