some people fear to get dominated from new players in other server, cant be best player and best guild anymore.
its understandable, i played few games before.
like :
Top guilds from server A, then server got merged, becoming rank 2932893723782th.
maybe the thing that people mean by revitalize, is by asking noobs and newbies to join WoE so you can slaughter them all
because in front of people that equally strong , its called unfair.
