That's a big thing. Sometimes I see molotovs come flying over walls/buildings from an unknown source and land right on top of players. And if I see one fly up into the air toward me, I move and then watch as it lands perfectly where I was.
It's that which annoys me along with the AI players being able to shoot while in a full run with one shot and hit you. It isn't always a one-shot kill, but the fact that they can appear to be running in a different direction and somehow shoot to their side and hit you is a bit annoying since I wouldn't be able to do that.
Of course often I enjoy the challenge but it seems as if the AI sometimes has way too much awareness of where you are, often before you have a second to see one of them, line up sights and fire. It doesn't seem as if they have as much as a human would have in an OODA loop.
