There's many private server around and also If is to leave game cuz is "empty" run to playwith Sea :P guess It wont close like the private servers... You spend money on those servers and It Ruin when the server close or be empty...
They Just could open a PvP server during maint like this some guys from isen/jainus or others can fight and pass the time till MT ends when they open the other servers Jin and Isen they Just close the PvP server...
