Why the fuck am I getting Plat. players in my Unranked Draft games.

I'm not even in a fucking division and I'm getting gold / diamond players in my games, WHY? IT'S NOT FUN TO PLAY SOMEONE WHO'S SO MUCH BETTER THAN YOU THAT THEY MICROMANAGE EVERY LITTLE THING THAT YOU DO WRONG. I CAN'T EVEN PLAY GAMES BECAUSE I'M CONSTANTLY BEING PUT WITH PLAT AND DIAMOND PLAYERS.
