You're lucky that the first person was actually looking away and not staring right at you, or the second one was actually facing you and got blinded!
I haven't played for a couple of days or so but the update/rotation is the worst I have ever seen in a game in my entire history of online FPS gaming, it's fucking amateur. The height of this was when a team mate was, on his screen; making a passable hole in a wall with his shotgun. Yet on my screen he was facing directly at me shooting his weapon.
This went on for around 8 shotgun rounds to the wall and reload.
It's a really good game, it's just in my opinion the one thing they should have got right before a lot of stuff.
I'm sure they'll sort it, unless they get stingy with the costs of how much bandwidth this will all cost when not letting us to host our own. Unless it's P2P and I'm talking shit but I don't think so.
