This is not an Mmo. Realm transfers happen on mmos. When it comes to Survival games… its pretty much standard that server populations go up and down based on content release cycles. When the next major update is released and the servers get wiped to add the new update check those same servers a day after. The population will be far greater.
I run a server and players always asking me to wipe the server because they believe players will all join once the server is shown as freshly wiped. I don’t wipe my server unless there is a massive gameplay update.
Currently this is slated as coming in September and thats when I will do so. Till then I try to have events for my players as long as my real life allows me to or my admins are on together to do it.
