About Duo boost
First game was good and I received RR for it. Next one game was worse than first and we lose. The next one with the same result, however in the match score I was higher than my booster. Generally, after boost I have less RR then before. Of course I don't wanna play with this booster after such experience. UPD: I have marked order as delivered because player spent his time and I realize I need to pay for it. About rating, of course my booster's score was higher in the last game, but only for a 1 point. I don't think it's normal. Actually, I won't place any order on BoostingMarket again
