Can call of duty be saved?

Can the call of duty game be saved from the funk of poor games we had recently? I think so modern warfare brought the first person genre to the modern day and did it with a bang. Featuring a real life special force team the SAS unlike the equivelant Rainbow six games which were fictional teams by tom clancy. At the time we need this realism in the games as jumping off point from the WWII games of the past. But then during modern warfare 2 things got silly with the death of roach which I didn't care about to the No russian mission that in a title like Modern warfare wasn't needed and could of been covered with a cut scene. But that brings me to the last 4 games Black ops, modern war fare 3, black ops 2 and Ghosts. The black ops games would of been made better with a mission like No Russian because that is what black ops are. Illegal missions that aren't recorded and remain off the record, I liked the no Russian mission it was just in the wrong game. Ghosts could of been an excellent stealth shooter it's not like they don't sell with great games like rainbow six and Ghost recon doing well but sticking to a wave based if it moves kill it game. They feel more akin to doom then a war simulation. I could talk all day about campers and how they are just the worst type of player. I won't but I will voice my views on how to deter it. Lets talk killstreaks the fact they are AI controlled (mostly) means things like the helicopter and attack dogs up the the kill count with no work  needed so they get the win with half the work. 

Look through walls but not be able to shoot yeah that works.

 Also in black ops II you had the mms scanner to try and deter camping but without FMJ's attached all it gave you was an area to avoid thus making it useless attachment to have. So in all it seems that Activision is promoting this type of dirty behaviour, yet worse they have had a glitch with sniper rifles for a while now. 

Look someone knows what they are doing.

You know what I'm talking about quick scoping because a mixture of perks and the auto assist it doesn't take to long to learn hell I tried it once and thought how is this a skill but taking it away cause the little kids that play the game to cry and kick up because it's unfair and they put it back in. This sort behaviour is why a lot of hardcore gamers are turning of Call of duty for battlefield, the realism is better. Also why not and destructible buildings it would change the game play no end stop the c4 throwing because they would think twice about double tapping that x button or square if your a ps3 player.
