Based off of Ispamchat's comment, something that allows you to record yours or anyone else's (on the same map's) previous shot would be interesting....you could save up to, say, six or something and watch them in the main menu. Also, you could record a whole game, if you wanted, but you could only save one.
@loolo: Most of the time when the game lags it's because you or for the most part your teammate has bad internet connection. Sometimes it's even one of the enemies, and I noticed in games like that when one of them quit the lag subsided.
You know the boss kinda deserves to die when the guards are all jittery and running around when they see you and the boss is just aimlessly strolling around, not even trying to hide
