Cycle of wins/loses to long?

Does anyone else have a problem with going through cycles of winning a majority of games then shifting to losing a majority of your games? because I find it really annoying to basically go through 10-20 easy games where you destroy more then half your games and then at some point turn around and get destroyed for like 10-20 games. So basicly I could intentionally feed during the hard games and the outcome will still be the same then play serious when I get put against easier players. I mean it's nice winning but it really sucks when you're in that losing streak and knowing that you're going to lose most of your next games. It would be nice if the cycle was not so long where the shift between losing games and winning games comes sooner so that you don't have to play 20 games and win maybe 5 to 7 of them. I've lost 8 out of the last 10 games and will probably lose 5+ more before it starts to level out a little. And I get pissed off every time I am in the losing cycle because I got so use to winning during the winning cycle.
