It will be great idea to open a side server.
example.
You Open a server in 10 at next month, )okay, alot of guys and pro and clans searching low rate server this time, but nothing is comming up. We are 40 people on my clan and playing on pvp waiting something comes up. I join here.)
So you open at 10/6 a server = people joining = people not living about everything is 80 = people staying and enjoy the game.
After 2 or 3 months u can make a great event with sieges and staff and merge the 2 servers to one again.
It will be bad for the other guys on the server ofc, but i thing is the on
