Yep the lag is real. I was playing aon black sheild, where I was in the room at the centre of the map, near upper heavy. I was hardscoping the doorway towards C flag as two guys strafe past it. I shoot one of them in the head, he doesn't take any damage and walks into the corner opposite the special ammo outside the door. I quickly follow up another head shot on the guy next to him and again no damage. He then walks into the same corner putting him completely out of my sight, I then die from him, from a headshot while he was behind the wall reloading. Green bars are a lie...
