DEAR RIOT, PAY ATTENTION

I have just seen a game of my friend in aram. There were 4 FEEDER BOTS in his team and 3 FEEDER BOTS in enemy team. Players who played legit had just an huge farm and score. The point is that if the grade is based on other champions performance HOW HOW HOW u beat someone who played against a full team of bots. It isn't FAIR.
