I think the best MM for Halo4 would be the old Halo2 setup. It was very easy to gain or lose levels and eveyone around your level was near the same skill level. Halo3 and on are kinda like Call of Duty to me as in the fact of You gain points For playing. That is pretty lame to be honest. You don't give awards to anyone but the winners. Halo2 matchmaking would balance it out more and bring back the old intense feel that Halo USE..... to have.
