The problem with zones that Particle's admins create (and ones that Tokath maintains) is that they aren't "real" zones. If we put them in the unused empty holes in the map, they'd just be out there in the 'unknown' zone, and when leveling there, you would be in "unknown" as well. Bots that get bashed off the map are in unknown too, so every 30 minutes, Zone Diagnostics would kill the bot(s) in your zone.
I've been getting around this problem by piggybacking the new zones inside the spheres of existing zones (eg, n00bzone is in Keldrin Mine's airspace. Demonzone is in Uber Zone's airspace.)
I suppose if you like your location being unknown, having no warning that someone might be sneaking up on you, and being subject to zone diagnostics, then a new zone out there in the boonies wouldn't be a bad idea. lol
