Just had a series of Bronze/unranked healers/tanks in my team, while I was trying to clear my Gold Promotional Series... Enemy team? Silver. Gold. Silver... Three times, I hit 900, and three times, I ended up with horrible matchmaking. And then the game just decided to pull out every last unranked player it could and throw it at me... Enemy SCH? Silver. On HER Promotional series. Mine? Unranked AST. So stupid.
