honestly like 70% of trophy winners on this website are bad players who only do well because they play exclusively with their group of usual people and can only read off of metagaming.
some people (read: other bad players) are literally night and day as mafia/town that if u play with those people over and over in a setup thats say 7 town to 3 mafia then you're going to win nearly every time u get town and probably half the time when u hit mafia which gives u somewhere around a 85% winrate
oh and lets not forget the casual grs/throw from ur buddy towards the end of the round always helps
