Well it looks like ETB was the only one working when it came to KD ratio, which helps with preventing team stacking. Why dont we go back to ETB, cause i know we are trying something else right now. So go back to ETB, and when the teams are unequal in size, which BTW ETB does when the losing team still cant win, it gives them more players to help them win. In the event that the teams are 15-12 or soemthing, admins can balance team sizes with one click in the admin menu. Why not bind a key to the auto balance team, and the team size will be even.
Guys lets not forget that those team balancers are here to ASSIST us, but not to take the task away from us. As admins, it is our DUTY to ensure that the game is as fair as possible for everyone, including stacking.
RULE NUMBER 6!
6. No Team Stacking. If the teams are stacked, then make it right, otherwise an Admin will make it right for you. Also, Please try auto-select when joining a game. This will prevent team stacking and also ensure that the side that needs a player gets a player.
