Lets see there are so many things wrong with the game it might be easier to list the things they got right (which is NOTHING!!) but here we go.
Lag comp, the camera angles are broken, OP pistols, aim assist is too powerful and pulls you off target when you are shooting someone, the SVU is the best SMG in the game, it is not a sniper rifle! (as a side note sniping in this game is far too easy, I suck at sniping and I can still get 15 kills in a round of DOM) SMG nerf while buffing LMG's, WTF is that about?? crap maps, head glitches everywhere, the list is endless.
I stopped playing COD because of this game and all the BS in it and probably wont go back to playing it when the next game comes out and most certainly wont but the next COD at release
