I don't have any issue whatsoever with lag. I live near Dallas with a 20ms ping to data centers on either coast on a 100/100 meg metro E connection (I play at work). In fact, to me, this game lags less than any other CoD I've played. I've never been disconnected and never seen a host migration. My only issue is the horrible spawns :\
I HAVE THE SAME FREAKING PROBLEM OMFG! And Its not just me either. I can go to some lobbies and have no problems -yeah i know its 1-3 shot kills in this game- but like one person said I can shoot buddy in the back 3 times then he turns WHILE IM STILL SHOOTING HIM, and kills me? Like wtf? It happens in most lobbies and i go super negative like 5 and 20. But in some lobbies I can average like 25 and 6? This was in black ops 2 And its here now? Could it be because we are matched with players who live half way around the world and not in our own regions? Its Crazy, they need to fix this. The more people talk about it the more likely somethign will be done. I cant stand ppl talking crap that I suck when I really dont. IT IS NOT HARD TO POINT A GUN AND SHOOT. But it IS HARD when you shoot and nothing happens. I have a friend in my clan 40 points a game in a good lobby, but when we play a Lagging lobby he says the same thing "I put the whole clip in this guy and he didnt die? wtf?" Si yeah there is a problem that needs to be addressed.
