Ok riot it’s time for you to do something

In the last game I played I had a 0/10 Yasuo on my team that got pissed off for no reason at our jungler and when we are winning he started intentionally feeding the enemy vlad and proceeded to then sit afk and call out positions out to the enemy team so we couldn’t even take objectives or make any plays safely. I don’t not deserve a loss or to lose lp for this game but I did simple because riot cannot step up and fix their system to compensate people for distraction like this.
