I don't think you understand what you are talking about - the game does not give the person a two tenth (200ms) head start on your location..... And change your server lag....
There are other ways of predicting movement of enemy players, either radar, or just listening with a good set of speakers can give a lot away as well. Not to mention a popular choke point, which you can just shoot down and wish for the best...
I can't stand when people confuse game mechanics and lag - and then throw around buzz words like GLITCH or AIMBOTS or HACKS...just saying....
I understand exactly what I'm talking about. I don't understand how you fail to grasp why the low tickrate of 10 is an issue and causes what I'm explaining.
I'm not crying hacks or aimbot, I've seen those in action and know what they are.
Lets say I am running down a hallway towards a T junction. I'm coming from the bottom of the T, the player I'm trying to kill because I know he's camping is waiting on the left side of the T junction.
If I come around the left corner on the T junction at 0.100 seconds, he will see me on his screen a minimum of 0.100 after the fact as that's when the server updates (every 10th of a second, .100, .200, .300, etc). So I have at least 0.100 seconds where I'm not even on his screen but I'm able to start shooting at him.
If I come around the left corner on the T junction at .150 or later, the server probably will update my location as still around the corner out of his LOS at 0.200 and give me an extra .050 seconds of action in which to shoot them before they re-act.
Vice versa, if he's camping that corner and knows I'm coming because I've made myself aware on the minimap through a previous engagement or a spot, or he's holed up on a well known choke point, he can pop around the corner and shoot down the length of the T towards me with the same effect in that I won't see his character update and come around the corner. for at minimum 0.100 seconds.
I've died plenty of times without ever getting a shot off while knowing exactly where some one is around a corner and being ready to fire but losing the tick rate update battle because they were closer to the corner and came around before I could.
But sure, go ahead, call me out for saying "Hacks" or "LAAAAGGGG" or w/e makes you feel better. This is a definite netcode/update rate issue despite what you'll pretend.
