The forum response, written by Aggrend, a WoW Classic producer under the name of Aggrend on the forum for the WoW community council's forum, delves into the way Blizzard takes on free character transfer servers, server merges and server merges WoW WoTLK Classic Gold. As Aggrend explains this issue, it's an extremely complex one without a "silver bullet" solution. She writes that "player transfer across different realms are among the most complicated and, in fact, the most complex issue that WoW Classic faces."

"There's no single-right answer for this issue, because different people are looking for different things, and lots of apparently obvious solutions have non-obvious consequences," Aggrend writes.

Server imbalances aren't new in Burning Crusade Classic or WoW Classic. Stories have long circulated about specific servers in old school MMORPGs being populated by nearly 90 percent Horde players or conversely. Oftentimes when a server looks to be dominated by a particular faction, guilds on the other side prefer not to suffer through it, will choose to move to a server with an improved balance of population. This is especially important in PvP servers that have a healthy competition between factions is crucial to the server's success.

Aggrend continues to provide an example of how trying to "fix" problems for specific groups of players with regard to server balance can unintentionally impact the experience of a lot more players than it aids. Aggrend writes about an instance where a PvP server has a player base that is 40 percent Alliance and 60% Horde. While most players would be content, a small portion of Alliance players aren't happy being outnumbered. Were Blizzard to allow the transfer of characters at no cost on that world, those unsatisfied Alliance players could transfer to a server that has better balance of population buy WoTLK Classic Gold. But the side effect will be that the server that the players used to reside on would become a 75 percentage Horde server creating a worse experience for players who were content with their previous balance.
