Congrats, you've beaten your opponents in a game mode where winning & losing gains you nothing at all. There's really no benefit for you to be this bad mannered towards your opponents by taunting them with "ez" spams.
Yes, there's a Mute button. Don't remind me. I'm just sad that attitudes like this is a thing in League.
