Sorry, I wasn't clear enough.
How to avoid, if at all possible that as soon as a tank has LOS it can see and detect everything, immediately.
I'm by the road, my engine running, some trees and bushes on my left, a guy, 200m away behind a tree is using his lighter while looking at my car... for half a second.
While playing should I imagine something like this or that I am in a Fairy Tale?, should I practice warfairy talegaming? ...the tank commander is always Legolas?
Yes, it is a game but if I deploy my troops -nobody was moving, the tank was the only one with LOS- hiding in a wood, for some reason my expectations are that they are hidden in a wood.
I will add even more trees and bushes and I will lower the crew quality... but something is rotten in Denmark I don't think to remember that CMBB was that easy for tanks.
