It would be amazing if it was some sort of ZNMish type system that was my favorite part of ToAU hands down. I'm not sure though with their wording of the 6-18 thing seems like if it was a spawned NM they wouldn't have mentioned a party/alliance limit. Seems Lushipur might be onto something, maybe a system like the weapon augment fights. But let's hope its not that either because the lines will be just as long. A BCNM type deal that up to 15 groups at a time or somethin can enter separately seems to be the least congested option available.
