The matchmaking balancing in this game is plain horrible

This is getting annoying, how many times have i played with a team of players thats on a loosing treak, not even have lvl 5 mastery main champions, feed like hell, all because they are playing against 400,500,700k lvl 5 mastery rivens and shacos and my team play a champion that doesnt even appear on their history of games once, like literaly they have only played that champ 1 fucking time and on MY ranked game to be precise.

The fucking game is not fun like this, all i see is a fucking team getting rekt 30-2 and my towers falling to minions while the enemy is doing baron with 2 people spaming the mastery icon every chance they get. It only makes me feel powerless and usless the whole game with 0% chance of come back.

You call this a fun game? this is the best online game in the world? 4 out of 5 my games are plain unfair and unfun one side games
