The answer seems to be simple. There is not any good server. If you create a good server,players will join to play. How? That's a great admin's job to find out and make it happen i guess. Then it's the advertise,the promotion of server,it must be everywhere and popular long before opening.
P.S. : Never call the gameplay balanced (or 99% balance etc.), Never say 'Unique' server.
Just saying,everybody opens a server and is an admin just by following a simple shared guide. But it looks like it doesn't work this way,it requires more.
