Is there a sort of thing the devs can do, in which X, Y, and Z level NPC's only will be cleared inside a designated number of miles from an active player city?

If that's done, I'm pretty sure a lot of people would be a lot happier about it. (On a personal note, I honestly wouldn't mind if Evony went and re-enacted Judgment Day on the flats 5-6 miles away from my own cities. lol)
