around 20 pop theres always around 8 ish afks most likely just waiting to play ze, add an auto-slayer that slays humans that havent moved after round 2 starts, then if they are still afk on the next map/round have them slayed at the start of round one, the reason for this is pretty simple: zmain farming dna for bosses on low-mid pop, if the humans who are playing dont give enough dna for the zmains then there wont be a boss, so essentially these afks are punishing the people who are actually playing the game.
