You obviously don't understand what I mean. AI detection through grass was very bad in the last game. AI can see you prone in tall grass as if it wasn't there, if somehow they can upgrade the AI so that they could react more naturally like humans toward it. The AI shouldn't see you when you are technically invisible to the naked eye. They done this in Far Cry 2 they can definitely do this in arma 3. Imagine hiding behind a bush in arma 2, the AI in arma 2 would still see you behind the bush even though you are 100% concealable. It's as if that bush didn't even exist. Now you see what I mean?
