I still completely disagree that "tryhard" antags are what prevents players from coming back. I have posted a video of me doing a friendly antag on Low Blow as Valeria...... and BOTH level 1 players disconnected despite me being friendly to them and the level 9 killing me every time they saw me. Once did in the middle of the mission, the other did after extracting but the THREE MINUTE TIMER having to count all the way down due to that previous disconnect, so the other newbie DC'd thanks to impatience.
People will disconnect and leave, antag or not.
