@ATOMXIILeaver penaltys never really work, for example if you get one all you have to do is go play something else a few hours and come back without a penalty so it never really teaches anyone a lesson and ends up harming players who disconnected, crash, get a random error, etc instead of punishing players who go afk or leave early
Filling in for the players who never made it in, crashed, disconnected, left early, etc is a better option imo or they should start calling off games that are not true 9v9s like Rogue Company does so you will at least start with a full lobby instead of half of one... sometimes it may get called off 2-3 (or more) times in a row but eventually its a full lobby but I think filling in would be a quicker alternative
