I don't know why but I actually like the repetitiveness of Call of Duty games. The only thing that annoyed me is that they once again let you get camos for your guns too easily. I remember the COD4 days, when you had to get 100 or 150 headshots for each gun in a class to get gold, but you only got it for one gun in the class. Even MW2 had 300 headshots for Fall camo.
