Solo Q vs Dynamic

I've done a couple dynamic q's now and i've got to be honest... I do way better solo. I don't know if I'm just going in with a different attitude? Maybe I'm going in thinking, "Finally, I don't have to carry a game by myself." But in reality I still do. I search people up, I look at win rates, kills, deaths, kda, and I play with decent people. But once in game I feel like their decisions aren't as good as mine and I lose a lot of dynamic q games. Where as solo, I go in knowing I need to carry, I go in knowing I have to do things to win the game.

Is it a mentality thing? Am I just playing with baddies?
