Let's talk about hit detection

Okay so I've seen a bunch of comments posts about the shit hit detection and I absolutely hate the way that the hit detection is. If we can go back and look at AW it was the exact same way. When the game first came out it was such a great game. Then with the drops of patches and dlcs the game slowly and slowly began to turn into a shit game with terrible hit detection and lag, and everything. Look what is happening again. I love the CoD franchise. My favorite. But this is the second year in a row that patches, updates, dlcs etc have made the came worse than when it first came out. It's ridiculous
