I couldn't think of any better name for this topic - w.e. What bothers me often (esp. in TW) is that when you hide behind a just small enough obstacle, it may seem on your screen as if you're entirely covered by the object, yet due to minor glitch/error/(whatever you wanna call it) on someone else's screen (and according to server probably) you may be partially seen. A simple way of fixing this is when you stop moving for over a second, your computer should send your specific location to the server so that it can correctly render your position accurately. This can also prevent the unknown walk in which you'd be standing, crouching, proning somehwere and the server thinks you're moving steadily in one direction - next thing you know you WARP there, dead. I'm sure most of you have experienced that at one point.
Simple idea, no?
