No players are ever synced. Even in other FPSs. I have a photo of a Gears game where neither players are synced and standing still and they are off by half a body.
Players out of sync is not a new thing. Play MW2 splitscreen and guess what they are out of sync.
You can go play BF4 but I will warn you. Its not even BF 3.1. Its actually a step backward. Enjoy the campers in BF games.
And so if those reasons below have always been a stickler for COD then why did you but it again and expect it to be gone ?
