Just made a smurf, and every single game is like this. It's a legit one sided slaughter because of how many smurfs are running around, and new players can't do anything about it.
Edit: Here are my other 2 games that I've played so far, see any similarities?
Daruis Afk'd because he was dying to a Riven smurf over and over, they had a jungler and we didn't so we had 3 bot lane.
50 kills in 17 minutes, just wow.
