he is famous on twitch, because he is simply the most entertaining streamer in history, no debating that honestly.
he is a genuine good guy aswell, if you'd bother to actually watch the stream instead of judging him solely because of some clips and his chat you would know.
yeah the teams he's playing are mostly not good but he's still putting up fucking >1.40 impact that's insane. In the few times he played top 30 sort of teams while on Chaos he was doing perfectly well.
both those teams are in EU right now and besides, BNB, Pain, Extra Salt all beat each other about equally it seems so they are all very close. I don't know if BNB are as good as Extra Salt now though after seeing them at FunSpark.
