It's not his fault why he performed that bad. I just watched post match interview and here what he said:
"I'm so sorry for devastating performance. I let my team down, or rather else Riot let my team down! I was wearing my favorite pants but they didn't allow it. I had to get strip naked on stage and change pants in front of crowd which ruined my mental coming into the game. I thought that was the only reason why I kept missing my shots until I found out that my windows was not updated which riot is responsible for and my mom forgot to wash my mouse pad. I felt really sad about this because I had to embarrass myself due to a lot of mistakes that's not even my fault! I will make sure none of this ever happens again in the future."
Feels really bad how he has to deal with so much hate right now. King will be back all goods.
