Why is every game a one sided stomp?

Queued ranked 3 times and every single time was an insane one sided stomp. I lost two and won one. Legitimately every game felt so one sided the other team never even came close to winning a team fight. Why do the games feel so awful ? Even winning like this is boring. I'm around golf 3 and the level of play is so insanely inconsistent it's just not enjoyable at all. I dunno if ranking up the lobbies would be more fun or if it's even worth the effort. I don't have friends to queue with maybe I need to add people. The solo q experience is miserable in this game. Even when I'm the best DPS in the lobby I cannot carry a bad team. And a lot of times the games feel absolutely unwinnable from character select. Do I just admit this isn't the game for me ? Too many sessions just aren't enjoyable at all. There's very little tug of war in matches its like either people have a basic understanding of their character or you get rolled.
