League of Legends balancing system is decent, but impossible sometimes.

Cannot change titel anymore, but i meant matchmaking

The match making system is great most of the times, teams with about even mmr and ranks (thus skill level most of the time), but lately I have come more and more with plats I or higher (up to Diamond I... I am silver 4, and last game we are (as shown in the picture) with 4 silvers and 1 unranked against 1 bronze II, 2 silvers, a gold II and a platinum III. lets just keep it at this; We got absolutely stomped that game. the score was 9/15/8 for our team... The Illaoi was 7/0/0 and the ezrael was 5/0/0. We couldnt take any objectives or they were there to stomb us. So why are there more and more and MORE very high elo players in my games, while we are around bronze I/silver IV -ish? It basicly ruins a game since we can not do anything to them if they are not boosted or whatever since they have much, MUCH more experience in sertain situations than I (or my team) do.

This wasnt the worst game so far. 2 Days ago I was in a game, with on our team (if I can recall correctly) a silver IV as me, a Gold V, 2 bronze 1 and 1 silver 1. decent team comp until we saw the enemy ranks. We were against 2 Platinum III, a Diamond V, a Gold II and a bronze IV... like, what is that matchmaking or what was it thinking, the score was about 12/50/7 for us. We couldn't do anything becouse they knew every move we made. So how is that even possible? its just insane...
