Guild Wars 2

So I was traveling around Fort Salma, only finding that centaurs are using catapults to destroy the buildings.
I decided to go to the destroyed area, and I see all the NPC’s just standing around, seeing their buildings destroyed. Although everyone seems immune to the catapult explosions and other kinds of damage, it’s real game breaking.

I find it understandable that these NPC’s became apathic and non caring. After rebuilding their buildings dozens or hundreds times, only to see them get destroyed again the same day, or within hours.

At some point they must have thought, why bother.
