TDK Kina (seraph) in rank

Not to call him out and attack his character, but seeing his twitter before it got deleted made it come off that he was an angry and not so nice person. Even in ranked solo Q, he acts childish. For example in his last Kennen ranked game on 1/25, he sold all his items and went trin force attack speed kennen and split push bot until his team lost the game. Other high elo players like zionspartan directly call him out and I think people will start witch hunting him and tell him to die, quit lol, etc. I know hes playing in challanger 5s and he needs to quit being negative or he could get banned from the scene, that won't be good because even if he gets banned from NA , the PR will follow him back to Korea.
