The following video is a bit offtopic. This video shows a complete (multiplayer) match of advanced warfare & one of its issues. lags (especially at 5.00). You can easily spot some lags towards the middle of the video & I encounter these frequently.
It has been announced recently that they will be fixed soon. Lets hope they fix it properly this time.
(ps:I am not using the shield.
I am playing cod multiplayer after a long time & am not good at it yet.)
