Noobs in Gold too?

My biggest pet peeve with the matchmaking system is how Riot sticks so many noobs in Silver games. Most of them are totally outmatched and they ruin games with terrible play. Noobs should be placed in bronze, as that will greatly improve the ranked experience for the veteran players who take the game seriously.

I spent 3 seasons as a Silver support main, playing my hardest in thousands of games, trying to climb out. So much is random in Silver with who you get on your team. There are many good players stuck there who've just had too much bad luck in matchups, getting too many noobs who hold them back. If everyone in silver had earned their spots the games would be much better quality and those worthy of gold would be able to climb out with good play rather than luck in teammate matchups.

I finally switched to Ivern Jungle main this season and have made it to gold 7 or 8 times already by controlling the flow of the game from my jungle position. Nevertheless, I always seem to get a streak of bad teams that send me back down. For some reason the teams I get in my gold games seem to be even worse on average than when I'm in S1 or S2. This last game (I was at 54 lp in G5) my 4 teammates had a combined 20 wins between them. I have 504 wins this season. The bot lane had a combined 2 wins. Of course they fed horribly and brought down our team.

How can Riot make such an amazingly creative and challenging game and yet be so totally clueless with their matchmaking system?
