Match making

So I’ve been playing for a couple of weeks now and I have to say this is probably the worst match making I’ve ever experienced in a game. I’ve been playing a lot of 3v3 knockout 700+ trophies for the main brawlers I play. Why does it feel like one game I get people that are playing blind folded on my team and then the next game the enemy is just like super try hard. Is it just me or does this happen when you play solo?
