We try to kill or raid any enemy that's online anyway, I'm sure most people do. As long as they're even semi smart they could hold onto it forever, even if they can't fight. The end would be awesome if it was regened every day or so and it was a completely anything goes area, you'll get a group who go in there and build a wall and stuff, or camp the spawn, but it's only gonna be like that for one day, something different will happen erryday and it'd be fun to have a zone like that.
