It takes forever to get into a lobby with friends because Killers dodge literally 80% of the time.
A 5 second cooldown is not enough of a punishment for taking the matchmaking into your own hands.
Perhaps, for each dodge in a certain timespan (day, week, or month), the cooldown increases further. To max of 5 minutes, or, even, to a 1-day ban.
Though really, it should probably be 5 minutes from the start, because there isn't any real reason why you would dodge a full lobby and then immediately requeue, unless you did it on purpose.
