I mean... The title says it all, implement a name change system for like 200 tokens or something. My last private server i played on had a name change system that you could use their subscription card to change ur name
Name changes don't occur because forums/ingame are integrated & according to higher-ups, it causes confusion within the server files I believe. It'd be wondrous to have the opportunity to change your name, only on a one time basis and for a high price that is.
No support. Adding name changes would cause technical issues with the server. Only way to change your name would be to create a new account with a different name.
