The ai have x-ray vision, you don't even get spotted by a enemy and you walk around a corner and instantly get domed. It happens alot to me with enemy ai on the technical, even if i'm behind 2ft thick concrete/stone barriers and posts they will instantly snap and ruin my face.

Also has anyone else noticed that sometimes the ai aren't even looking in your direction and suddenly they insta kill you or a grenade comes out of nowhere and blows your ass up.
