Riot's Matchmaking
I am quite tired of playing games where we unranked are facing off against Plat+ players. Yes I know it is norms, but Riot needs to fix this problem quite easily. And yes, I am aware that the only reason these players are in the game is because of being queued with another player. The solution is quite simple and implemented in every other game known to man. The game places you in regards to the highest player in the party, not the lowest. You want to play with your Plat, Diamond, Master etc player, then you are queued with players of that caliber.
And please don't say, use it as a learning experience. A high level player, with full rune pages, masteries, hundred if not thousands of games always, I mean always, walks over their lane opponents. How are you supposed to learn how to play if you die every time you are alive. So because of shitty, stupid and quite frankly broken matchmaking, 7 players learn nothing new, have a shitty game and that one high level player goes 30/0.
I am sorry, but landslides are not fun in either case, winning or losing side. The best and most enjoyable games are those where the game is close and can go either way at any time.
