What are you guys talking about? It's a tournament, not a get together of civ players. The whole idea of a tournament like this is to try to move up and then stay as high as you can get. God is completely right, if you get moved down, so what. If you REALLY belong in the higher level, just whoop up on everyone the next month and move right back up. If you really dont belong in that level, you wont win the lower level either, and you'll stay there.
Remember, it's a tournament to see whose really good and who is not. If it become voluntary to move up or down, count me out. I can voluntarily move up or down in my own games, I want to play this tournament for the competition.
