Am I the only person that doesn't like tracing line of site between diagonally places blocking terrain? I've always looked at those as a continuous wall (despite the fact you can walk between them - which also doesn't make a huge amount of sense to me).
What if they're not continuous? What if they're supposed to be piles of boulders? Those usually taper towards the top. Hence the view in between two distinct mounds not orthogonally adjacent, and the ability to step between them.
