Given how fast a "war" can be won in AH, having it end in minutes when someone exercises the nuke option would be relatively accurate. It would be interesting if nothing else. Imagine 200 when a nuke goes off in the middle of a giant low alt furball or a busy tank town.
It would be a pain but if allowed once or twice a year would be something to talk about. Nothing wrong with Santa, the Claw, or giant squids occasionally.
