Ranked matchmaking is so lopsided

I keep getting every game completely lopsided out of the last 20 games ive only won 4 the rest have been complete stomps barely taking a turret. This is getting to be bs Riot. Why do i get every feeder team and the teams that run in one at a time to die while the nemey teams group and objectify like they are 2 elos higher than all my teamates. Its getting really old Riot. Change league back to the way it was in season 3 when people could actually solo carry games and didnt lose cuz they had more feeders than the enemy team.
