I agree too.
By the way, what about the Clanner's po? If I'm not wrong, the clan has to play 30 games? that's too much as I see, playing at least 12 games would be better, is not so easy find a tus clanner and less  other clan agreeing with playing it. As example, clans like CKC or CF, it's not hard to see in their played, that not every clan wants to play against them, well I can't see the games played by CF at all because when I try it displays the games played by my clan xD. Will be a shame if those clans can't get into the PO only due they couldn't play 30 games

Also, I don't think that is a good idea have the 50% at least of games won. Clans that reach a not bad rating playing against anyone are better than a clan that have the best rating only avoiding clans with better players, therefore, delete that stipulation! avoid noobashing!.

Edit: Rofl xD why I have -1 of Karma xD. c@#!s! I'm the most friendly wormer haha.
