In a 4v4 Elimination match, why do we frequently get matched up against the same opponent multiple times? I'll often get the same opponent 2x in a 3-4 round match, and even got the same guy 3 our of 4 rounds in one game today.

It seems to me that we should get paired up against each opponent on the opposing team, and if the match goes to round 5 then the pairings should be random.
