DDT your skill system forced people out from Xsyon, tons of people left because of skill system, an your decay system and many other things suggested by you forced people out, I do a lot of pvp but not in Xsyon, FYI. And I do know what people want.
Fix skill system and you will see if people return. This is one of many things need to be fixed, give people PVP flag system and PVE server will have players playing but not PVP server.
You are mad because pvp server is empty, really it is pvpers fault in the first place.
