player matching system broken

With like 50,000+ people always playing this game, why is it that I will get that same(mostly trolly) people in my games back to back. I should never be matched with or against the same people that were in my last game ever. This has got to be fixed, as it's part of why this community is so bad. People yell and fight with others, soooooo you put them all back together in a new game. Seems like the game trolls you just as much as the players will. Freakin Genius. Its no wonder this game is notorious for how bad the community is when half of it is the game itself. sigh.
