Most PUBG streamers are just so off putting with how they react to being killed. Every time they die it's bullshit for one reason or another, I can't believe it, what I shot him so many times, omg how did he do that, that's shady, I got stream sniped, etc etc
And let's just say it's true that dozens of people are sitting around at the lobby waiting for you to queue up and hoping they guess the right server region and queue up at the same time to get into the same game and a bunch of them consistently make it into your games. Even if that's true you're only validating them and making their efforts worthwhile by complaining about it and pointing it out.
I wish more of them would just roll with it. Dying isn't that big a deal, just move on to the next game. Only cohh and sacriel seem to be pretty consistently chill about it and cohh only plays it extremely casually. Anthony is usually pretty tolerable even if he does complain -- but only because he's funny and good humored. He doesn't frequently act butthurt.
