Such threads was not uncommon to see in wow or mmo with toxic players, where exists people that want game to be played by their rules. answer is simple as usual don't pug with randoms . find friends that play style suits you and forget randoms. but if players pugs and complains about randoms it's bit weird.
From my opinion if i'm with randoms i can expect everything from afk to trolling, kick, fail in sastasha 20 times etc. if it's goes beyond my limits i will leave party and that's all. it's not a job for me but to have fun.
why i said toxic players because they are playing not to fun have but in always rush, thinks that everyone in random party cares about their dps/heal/tank numbers. they create own rules in random pt and complains when nobody follows. just think for moment - play style and things to achieve in game are different. if you complaint don't pug with randoms and create misery for everyone.
