Walls that really break
Low walls and boundary walls leave jagged stumps and scattered stones when hit, different every time, on every map.
A low wall hit by a shell no longer turns into a neat step: it leaves a jagged stump, with stones scattered around and pieces of the coping on the ground.
Every section breaks differently, and the rubble stays where it falls: players who know the map know where to find cover after the first minutes of battle.
