There's this phenomenon in competitive games where people tend to push the blame into the team players and that they are worse and lose your games, think about it this way if you're better then your rank then the enemy team will lose because they are equally as bad as your team mates and you'll be able to carry the game,. If you really are stuck at a rank then that means that's your average potential and getting out of it isn't supposed to be a grind, when you get good enough you'll eventually climb. Rants about competitive are always senseless.
