what people complain about is the quality not quantity.
let me explain, here is what happens;
people including me give some effort to play better matches with both teammates and enemies, and we start a winning streak, lets say 8 win in row, isnt that amazing? yeah but everything end eventually, end we lose, whats wrong with it? nothing, but problem is not losing problem is the reason why we lose, we accept to lose a better team better picks tactics play etc, but we cant digest to lose cos our teammates getting noober and noober as we keep winning. We are complaining about QUALITY not QUANTITY. I hope I am clear.
In short: People expect to play better matches the more they win, but happens vice versa.
