Rediculous matchup statistics - Someone PLEASE explain how something like this can get stacked so ha

This is so freaking insane! We literally had 5 completely brilliant players on one side, and guys who were on tilt and can't play strongly on the other..... I literally cried as I loaded up the stats on the loading screen. A kog thats averaging 1/7 and on tilt, 3 guys with K/d/a thats even and me with high cs. on the other team its 7/2, a god support, 11/5, and a 12/9 but insane cser...... game ended 18 minutes in 2 inhibs down gg. didn't even get time to surrender......

Rito please.... balance mannnn
