Your ideas are fairly extreme, and in my opinion, not well thought out. I?ll lay out my disagreements in simple, clear points.
First off, call of duty is both for casual and hardcore gamers; I know lots of casuals who purchase the game and get into it due to the amount of friends they have playing the game online.
Secondly, I don?t think you can make the argument that the series is getting worse, Blacks ops was a better game than world at war, and modern warfare 2 was both highly reviewed and played.
Thirdly, with black ops released, I have seen extremely few noob toobers, and even if there are some, it?s a weapon, which is realistically placed in the game (I?ve fired one).
Fourth, you may not think they have made a good COD since 2007, but every national reviewer, and millions of gamers who purchased the games would disagree with you. The majority of people purchase Call of Duty for the online play, it?s a huge and fulfilling experience, why should they remove something good, that works, from the next sequel?
Fifth, if you love single player games, like fallout, then buy those games, COD has always had an average campaign option, sure it?s stronger in some games, but it?s never really been amazing, at least in my opinion. I am a fan of deep, single player games, this game is my multiplayer experience, don?t take it away from me.
Sixth, if you don?t like the attitude of online players, don?t use the mic, mute players, or play with friends, it?s really that simple.
