I think what this guy is trying to say is that the "3v5 rule" is formulated wrongly. I will simplify the rule as an obvious example: "number of players in opposing team is greater than 3 you are free to leave;". So it says: if the number of players on the other team is greater than 3, you are free to leave. If you start a 4v4 game, youre free to leave from the start, since there will be more than 3 players on the opposing team! Result:
player on sentinel, mode -apso
3 players on scourge --> not free to leave
4 players on scourge --> free to leave
5 players on scourge --> free to leave
player on sentinel, mode -ap
2 players on scourge --> not free to leave
3 players on scourge --> free to leave
4 players on scourge --> free to leave
5 players on scourge --> free to leave
Ofcourse this is not the meaning of the rule, but right now it simply says the wrong thing. It can be easily solved by changing "number of players" to "player difference", resulting in:
If the difference of players between the two teams is 3 or greater and the game mode includes -so (-switchon), you are free to leave the game without ban;
