Theres so many old zones, old old zones, new zones, I am getting confused.
I don't think this big guild war would work, they boost the playercount on gk because there isn't normally a lot of PvP. On zone all there is, is pvp so a war between two "official" guilds won't change anything. Also I wish zone would go down to classic and get support by the willingly-to-work-for-FREE people who never get gold.. but its a low chance of happening.
P.S(maybe if you said a zone 2.0 is coming out like delteria, it would get highest playercount and then die down after about a week)
