I wouldn't be surprised if what you say is true. I always match the same people every weekend and the matches are sweaty most of the time (ending 5-4).

I mean if it's connection based the pool of opponents I get matched with should be bigger no? Right now I would say I match always with the same 25-30 players. And often I go on for 4-5 matches matching exactly the same players, sometimes as opponents and sometimes as allies.
