If Bungie implemented this type of matchmaking they would need to match the teams based off of the player on each team with the highest number of wins on their card. (To prevent boosting) A great thing about this type of structure is the final few games should be exhilarating. Hopefully the result would be that the matches progressively become more challenging and ultimately the final victory more gratifying. This structure would also help negate the argument from that the current structure is unfair as a group could get a lucky chain of poor players and thus gain easy access to the lighthouse.
