I don't think Matchmaking is your problem. I had a look at your stats and gear. Your weapons are not remotely competitive even for quick play. I'm not saying you have to use the meta but you're using Wardens Law on your Hunter and Sweet Business on your Titan. Wardens Law is used by 0.0530% of the player population according to https://destinytracker.com/destiny-2/db/items/233423981-wardens-law Maybe matchmaking is part of the problem but you'll have more fun if you stop using garbage weapons.
