I start to think that unlagged is a problem and can be exploited in one way or another : I've spected , recorded .... many players hitting , destroying their opponents while crosshair was neither exactly over their enemy.
Yeah I think this is because you might be watching the servers view of the client or something to that effect, but I have no actual knowledge of how the spectating system works. I always notice 200 pingers hitting rail shots where the player is 10-20 feet away from where it says they are aiming when spectating. Their client says the player is where they shot, but in reality they took that shot at the location of the player 200ms before they shot. Unlagged makes it more playable for higher pings, so I guess its a good thing if you are a high ping.
