3 to 19 slaughter on a feeder team yet its "my fault" according to the idiotic forum posters

Seriously starts with zac running in and starting a 3 v 1 dying to my laner right before yasuo runs in giving him a double. He comes back with a blasting wand already meaning he was way ahead of me. Then bot starts feeding jinx like its their job sivir going 0/7 blaming it on her 1/1 morgana and yasuo starts feeding the mid and jungle going 0/6. I was trying to survive the fed veigar and farm to catch up staying at 0 deaths but everyone fed and quit protecting their lanes so i got 4 v 1 twice before losing my tower too and after that the game was completely sht on as we took no turrets.

All my fault right? Get gud? You guys are morons this happens way too often that one team just feeds and the other team seems way better than them. The matchmaking in ranked sucks plain and simple. No matter how "gud" i get it does not change the fact that i have to single handed be able to 1 v 5 to make up for the teamates i get when the enemy team does not share the same handicap. Riot seriously needs to work on their matchmaking the removal of solo queue made ranked enough of a joke we dont need bad matchmaking algorithms just to shorten queue times on top of that.
