Poor winners are the worst. Have a post game chat mute option.

I need to break from this game for a solid month. I've been on a losing streak, and most games end with a post chat shitshow that gets harder and harder to ignore. My rage is apparently beyond my control, and it gets hard to not respond to the keyboard warriors. I just need to take a solid break, clear my head, and figure out how to do a blanket mute on ALL chat. That should be an option riot. Post game chat mute. Sure, you can block the toxicity in game, but it's a free for all afterwards.
