Yeah same here and when I look at the killcam in my game I'm running behind cover and in the other person's point of view I'm out in the open getting shot.
I know it's not my connection because I have the Fios 100mbs too.
Another thing is it's hard to go on a run and get killstreaks. Killstreak rewards are few and far between. The maps suck that shipped with the game and I heard the good ones are coming in DLC. There is so much cover, head glitches to hide behind and almost everyone is doing it or camping for their streaks. The overall system to the game sucks too with the divisions and all that. The pick 10 system that Treyarch does is perfect, but this system they have in place is terrible. It makes classes so limited and like no type of variety either. You can't have fun playing the game anymore because you have to tryhard almost every game to do good, and that includes playing like a biaotch and crouch walking, hiding behind ****, camping because the other team is most likely doing it too. I mostly only play core TDM and I still can't believe it's 5 kills just to get a UAV.
I see a lot of youtubers complaining about the skilled based matchmaking too, but SHG is known for that so it is what it is.
