He was in Bronze 1 or 2 he plays horrible with cait and suddenly in one night it had a win streak about 20 matches with cait and he entered silver , I dont think its elo boost because of his scores and farm and I talked to him during some matches , I queued up with my smurf S3 and 2 times in row (2 games ) we were queued up with unrankeds that played terrible ,and we won.
