The matchmaking algorithm in crucible and Iron banner is aweful. Numerous times Ive gone against a 6 stack (which is fine), but after a mercy loss, and Destiny "switching up the teams", Ive ended up against the exact same 6 stack, only difference is Bungie swapped out my good players for new light players. You would think they would take into consideration people in fireteams and single players, not putting a 6 pack against 6 freelancers.
