There are many private servers, freeshards and even retail MMOs that regularly run 3-4 month Seasonal, fresh start servers that either expire, or bring characters over a certain level range to the main server with the season ends.
This is a great way to refresh early content, bring in *tons* of new players, and let everyone compete from the same footing.
Would love to see this game with several thousands players at all times for a couple months

Forgive me if this has topic has been beaten to death, as I couldn't find any other threads on it.
(also please dont murder me for asking cause I full understand the sunk cost of this game and they have every right to be proud of their characters and guild's accomplishments. Rolling over seasonal characters to the 'standard' server when the season ends alleviates this)
