Ran for over 2 hours by myself last night in core tdm.
Paid attention to the hit markers and for the most part was dropping the enemy in 3 to 5 hit markers.
Said this for the following -
Try running in core if you are getting more than 5 hit markers take a serious look at your connection.
Pay attention when you are playing with others too.
It is no ones fault but with the internet infrastructure in the NA not all of our connections work together properly.
This is why I also emphasize on working in squads of 3.
I only push this for our competitive game times when the wins really count.

Yep I notice all the time when running solo i drop the bad guys real quick.and also run with all four bars all the time sometime three.when I get lag at times I check my Internet and I am always running 40 download and 6 upload.but still get lag in Advanced Warfare and I don't know why.with speeds like I run I should be lighting fast with know lag.but when others don't have good Internet I thank gamer's take the big hit with great Internet.who knows at times if COD would get some Servers up we would not have to worry about this lag shit....

It is a crappy connection when I play the game by myself. I have good internet and i die over and over where i didnt get any notification I was hit until I die. Then the killcam shows the guy just pumping me full of bullets like I was just standing there asking him to shoot me.
