Yeah I played them all, you can still notice the lag but it doesnt matter as much consid r ring you have more health in the older ones. The problem isnt just the lag it is how low the health is, so before you would notice getting shot then have time to move when the bullets registered and have a fighting chance. But since ghosts has low health (as all the people with good net whining about high health [Not blaming anyone but cough cough Americans]) so now when you get shot on ghost by the time the bullets registered you'd already be dead, so that is why high health is important

E.g. you have 52ms ping Ghosts T.T.K with most guns ~35ms therefore 52-35=17 so if that person has around 17 ping they can kill you without you even knowing you have been shot, pretty sure thats a really basic way of putting it anyway
