Mendon's Gap

[Svarty.8019]

So the now-indestructible wall on the west side of Mendon's Gap prevents entry from that side, but you can still destroy the FRONT wall from the same old siege spots by shooting the corner. So what is the point in making the side-wall invulnerable, that being the case?

For the record, I like the idea of forcing attackers to take more risks, and would like to see the front wall made invulnerable, too.
