unfortunately we had to make this rule because the last month the firts and the second of the league the last day instead of play between each other, they play with the last ones to earn easy points and get advantage.
This was a moral rule, a code of ethics among users but the times changes and there's no more ethics codes, so we have to make it a mandatory rule.
If you get the 30 match the last day unfortunately you can not play for the championship but you can ascend, dont worry.
