In single player you rely way too much on cloak.If you are not cloaked you must be like a giant "SHOOT HERE" billboard,because the enemy 100 meters away looking at the stars will see you immediately and fire
Also,even inside grass,cloak runs out,everyone on the city sees you.Inside a bush.same thing.In the night standing still inside a shadow surrounded by tens of ruined buildings you expect to be unseen for at least 5 seconds.But NOO,the SEE ME THROUGH THE ONE BRICK MISSING.
Come on.I'm wearing a freaking grey/black suit in the dark,yet i'm as visible as a pink Hummer with christmas lights and a train horn
Even C1 A.I was not this stupid(in the sense of not behaving like they should)
