I EXTREMELY dislike the matchmaking system

Seriously look at this match. I started up going 3-1 and our toplaner was 2-0.
Started off that Velkoz died three times at his lane while i was spam pinging where Rengar could be (he was base and my mark was on raptors and got his 6 out of it, obviously he is going to gank midlane) but our Vel just didnt wanted to listen to me. THIS LITERALLY HAPPENED THREE TIMES. Botlane died really often early and gave me the fault for not helping them in a 4v2 situation while i was at top side. Afterwards their team just got overfed and just stomped our ass out of the rift. Shen kinda lost his shit and started to hard flame botlane and midlane which turned out to be an massive disaster and everyone just didnt wanted to play anymore and pretty much hard lost this game. And oh well, it was obviously a game after I lost my promos (my promos were kinda the same experience, though my 2nd try was really a success because I actully had a team who was really open and tried their best to listen to me) and it was also 1 game before I got into my promos.
