why not just make 2 nations?
I was also trying to make NW 2 nations only, but weird things were happening Imho 2 squads that actually know what they are doing in the Light nation would be enough to make it first or second. It seems that now people purposely re-enter till they join Frost. Before when there only was 1 pass, Flame nation was always the "bad" one.
So many nation wars threads end up on the same conclusion. If people stopped leaving light and fought like everyone else, the nation would have a chance of winning. It's not about changing NW, it's about changing how players think.
