No. It is you who is not understanding. You pop out and they pull the trigger when you are out of cover. The game has no bullet travel time. It recognizes you were killed but because of lag it didn't register on your Xbox until you were behind cover. As for snipers taking no skill, well that is just a stupid comment made by a salty individual.

Umm I play PlayStation not xbox an you don't understand that that's not how it should be if your already behind cover an get killed by a sniper that you dodged before they even fired the sniper is broken (you see the sniper you quickly get. Behind cover before the guy shoots an you still die) that's what im trying 2 tell you an I was the shooter that got six people three weren't headshots they were shoulder shots or collerbone shots an the other three I shot after they were already threw a door everyone was green bar an there was no lagging in that match

The reticle has to be on the head for a headshot. If it looks like anything else it is because of latency. His head was there when you pulled the trigger.

Well whatever the guys I shot in the shoulder or collarbone it said head shot when I shot the ones that disappeared behind the wall it said headshot 5 seconds after I pulled the trigger so snipers take no skill an are broken
