I know, I know. I just moved forward a bit and presented the other side of the coin. If you are in prepared position and click on someone who is just in your range, but he moves back, you follow him which leads into random deaths too (and is also something unintended).
With both these thing you just need to be careful and be ready all the time to manage your position more that just focusing on shooting. I personally don't mind, it brings some challenge in proper usage of full range/hexshooting, but if it could be fixed easily, it would be better. But what I'm afraid of is it's engine's fault, not some scripting.
So I just gave a similar example and will leave it here for someone who knows what to do with it to read.
