Wall concept

[Philosophy101]

I have this concept on how walls can be more useful. In the real world walls don't just prevent people and objects from going through, they also block visibility, hiding whats on the other side. So with this concept, walls hide whats on the other side from opponents. Example in pic (Left is how it currently is in bfme 2 : Right is my concept for Reforged)

[Lostir]

Walls have never really played a part in competitive multiplayer and aren't really something that should be expanded on.
But I agree on more distinctive vision like you described.
In general there shouldn't be vision behind obstacles, and there should also be things like forests which reduce vision.
