I guess 4 guild's are enough. 3 Attacking guild's and 1 Defending. It's still interesting.Much participators, much intrigue and lag.The only thing that can happen is Server 5 will be always full and you may never enter plus the lagg's will be increased :/
This is fail... First of all i don't think that the administration team can do something about that, it's up to webzen.
And second, imagine what lag could be in there...
