I personally have no problem with halo 4 MM. It is not supposed to play like the other games, these are different spartans, on a new game by a new developer… Im happy its a different game, dont want to get stuck playing the same game for years on end.
And if you really have a problem with it, go play halo 3 and reach 
i do that sometimes… but now we have a new game with a new feel…
ahh refreshed
