Well X-101st was one for the 1st well know clans that started it but a year b4 they were made I rememeber an old clan of mine had a 3 way war with UC and EW.
Well that would not work in that case it would be more of a who has more memebers thing. It would be better if the clan gets a Point if they kill an enemy clan memeber at one of the 2 places.
