Ya'll need to work out the teaming up bs in game. With either a monitoring system or proximity filter that won't allow players to work together in killing the last man in classic ranked/unranked mode. I've played numerous matches, lost numerous matches, because the last remaining players, not on the same team, but mutual friends, focus on another player, despite they are to kill one another. This happens a lot in solo, duo and quad. Should be considered cheating, because it is extremely unfair.
