Call of Duty copied ideas?????(Black ops 3 Gameplay)

*So before typing that i am totally wrong in comments section hear me out. Call of duty franchise is one of its kind but in the meeting of Activision and Crytek,Activision agreed that the ideas used by Crytek in Warface was good as they made a lot of money.Activision later used the ideas which Crytek described how they were sucessful using the ideas.The same ones are in Call of duty now. Your opinion are welcomed =) ,But not hate please. Be nice to everyone in comments and dont spam =).
