Is Doubles matching horrifically imbalanced?

Or am I just REALLY lucky? If you look at the majority of my latest Doubles games, you’ll see what I’m talking about. Most games I’ve been getting into, I completely dominate the opposition. I’m really not even THAT great at this game, average at best. But some of these matches I’ve been getting into makes me feel like I’m a Champion. I find myself carrying my team mate in almost every game I get into. I was in a game yesterday where my team mate had 2 kills and 2 suicides. I had 25 kills and we won. I’ve had multiple games where I go 20+ kills and less than 5 deaths. It seems like usually there is always one good or decent player per team, and the other player on the team is absolutely awful. The times where I’ve seen 2 good or decent players on the same team, that team usually comes out on top because someone on the other team has no idea what they’re doing.

So is this just a lack of skill based matching? Is it a population issue where not a lot of high quality players are in the playlist? Or am I just getting into games with players that are usually bronze/silver when I’m usually high platinum/low diamond?
