Have a great day guys!
Thought I would share this in the hopes it will brighten some of your days. I played with a really toxic Udyr who didn't gank for the first 15 minutes of the game and would just run into lane stealing farm and experience (as well as revealing his position so the enemy team knew where they could exert pressure.) Then he flamed the team when we started falling behind and dying. When we tried to farm jungle camps in order to catch back up his response was "stop taking my jungle camps %%%gots." He purposely would smite blue away from me (our mid laner) and purposely would smite red away from our ADC (even when we were 30 minutes into the game.) I wound up muting him since he was putting me on tilt. When the game ended he continued to flame us in post game chat telling us how bad we were. I reported him and then replied "Enjoy your ban Udyr. gg"
Little did I know I was going to get this little gem once I left the post game chat. Ahhhhh....justice.
TL;DR Keep reporting toxic people, it does make a difference.
