Guild Wars 2

I was kinda disappointed with orr, the preview made it seem like WvWvW but against bots.
That didn’t happen though, everything was “static”, I kinda expected roaming groups of mobs attacking points, but in reality it was timed events that spawned mobs.
This thread isn’t about that though. If there was a new zone, could we actually make what I wanted?

Could the event system be more “sandboxy”?
I’ll give an example.

In a new zone, a wandering group of enemies homes in on a nearby town on their own accord, with AI or something. It starts an event to fend the town off. If you fail, the town is destroyed.

Now, instead of the enemies re-building the town, what’d be stopping US from re-building it? Maybe we have a limited amount of supply and have to choose what buildings we can remake? What if the town can grow?

It would be fairly difficult to implement, but it would be great (until people find a way to abuse it for gain at least, about a week).

Thoughts?
