Matchmaking System and my Negative Eperience

Though I may be Bronze IV, I have been getting games that I'm either matched with very new players, or against players who are using tactics that are seen in Platinum - Diamond level play. I play league to relieve stress caused by other things going on in my life, and to come in, and get unfair match ups, is turning me off of playing this, though sometimes frustrating, amazing game. I feel that this game is no longer what it used to be. I have experienced that the reporting system is also just there as a placebo. Being a semi-active member of the Beta testing community, I'd love to share my ideas of changes that could balance several champions, but my negative experience has made my decision to quit League of Legends. I cannot play this game casually anymore, and I feel it hasn't been that way for many seasons. Riot Games, I wish you luck with the future of League of Legends, but I am no longer supporting this game, because of the bad community, and the seemingly lazy work to fix the gameplay of many champions.
