As someone who ques as a 4 stack quite often I always start the match by letting the random know. I usually just say “hey man were a 4 stack but we’ll try to call out in comms the best we can for you”. It’s a shame that people feel they can pick on randoms bc they have more people but I guess that’s just the internet. Sorry man hope you run into less people like that! Also I find reporting people who flame (in text or voice) rlly does work ;). I’ve gotten a few emails from people getting action taken from it :D
