Lee Sin from last game trolled so hard

He bought void staff and refused to play with the team FOR NO REASON. No one was toxic, in fact, barely anything had been said by anyone but he took it upon himself to throw the game we could have easily won. I don't even care if this is naming and shaming... I can understand if someone was toxic to him or at least have SOME reason to troll.... He literally just trolled and threw the game because of no reason. He made sure to sell the void staff and buy real items before the nexus died though, to try and escape punishment.
