Enemy AI needs work

They are very dumb and have no sense of preservation, they don’t seem to take cover and when they engage in combat they just ran from one side to the other shooting and in a lot of times they will get rid of your armor as soon as u start a match, this problem makes a gun like the bolt rifle useless since there is not reason to use it. Trying to play stealthy is tricky or impossible because sometimes they wont notice u killed an enemy right by their side and other times as soon as u kill one enemy their buddies will instantly know your locations. It just feels like engaging them has no proper flow.
