Ok so I just had a match where the opponent team was one player down for the whole game and we pretty much obviously mowed the remaining two opponents down, round by round. And just as we were about to finish up the 5th round, with a single opponent left alive (and in the middle of a firefight, so it was just the matter of time when he drops), the game literally put another player into the instance to fill up the fireteam, just for him to instantly lose and I was able to see he had a flawed card because of that. He might be at the beginning of his winning streaks, or potentially even his very last game before getting flawless, the point is the same - why on earth would the system do that and force the poor dude in like this? It's ridiculous.
