Fast paced gameplay taking all the skill out of game since who ever gets the first shot off wins. Also Flood replaced infection and 343 took allot of features out like flood cant hold guns which killed allot of custom games and flood in matchmaking is absolutely retarded with flood thruster packing their way across the damn map and being 3 headshot kills. Oh and all the fun playlists like grifball, snipers, swat, and actionsack are in rotational state.
