Why I feel like I don't want to play any more

Now I know many of you are going to say that I am just whining about this because I am bad or something like that. But that will really just prove my point a little. I have played LOL for awhile now (since S3) and enjoyed playing it was fun, challenging and people were cool, and I feel like that has been lost with this game growing so big. I am Gold 5 and I willingly admit I probably belong there :P But I feel like I cant even try climbing any higher because of this game being so random. There will be games that I win by a land slide, others not so much. But there are always 3-4 games out of 10 that someone is not playing good, flaming, being toxic, feeding or afk. I don't remember having this much problem in S4 at all. I can't get better because I can't even have the same level players all the time. How am I to perfect timing, moves, etc. when I can't even get better players to be there. How am I to climb when I have feeders or afkers? I have friends that played longer them me and admit that this community has really gone down hill. Riot I know you cant change how people play or act but I feel like I want to tell you that I really don't care for the game anymore. Nothing is fun anymore because people take this game like they are in the worlds championship or something and when they lose they get all bent out of shape rather then brushing it off.

Does anyone else feel this way?
