This Matchmakeing

So i just had a game of Ranked with my friends we were off to a good start and then they started to win and they roamed to out laners meanwhile our mid laner Vel,koz UNRANKED with two wins was 48 farm in 28 mins was shooting the magical things that were not there and ulting his team mates and farm to try and get it.After they all tower dived us in bot lane i seen that he sat across the wall looking over doing nothing as 4 of them dived us. In a burst of anger i type to him "WTF" he reply's "At least im doing better than you" he was going 2/10 i was 8/6. ohh and btw im silver 1 was 40 lp. RITO PLS FIX YOU MATCHMAKEING AS HE WAS UNRANKED AND PLAYED TWO GAMES AND HAD NO IDEA WHAT HE WAS DOING PLzzzzz
