In a post on the World of Warcraft Forums, Blizzard explains they are planning some server merges in World of Warcraft to improve population density in the MMORPG (thanks GamesRadar+). Word is over the next two to three months lower-population realms will be relocated:

World of Warcraft is best when you have a community of other players around you, and while numerous ways to participate in cross-realm play have been added to the game over the years, there are still many aspects of the experience that are realm-based. From your history with your guild to your interactions with the economy around you, a realm with a healthy population provides more opportunities, and it’s been several years since we last connected some realms.

We’ve now completed a comprehensive study of realm populations for every realm in the world. Over the next 2-3 months, we’re going to connect the low-population realms to other existing realms. This process will take place during scheduled maintenance, connecting a few realms each week, until we’ve connected every low-population realm in every region to a substantially larger population of players.

As this project unfolds, we will post notices in advance of each week’s connections in the appropriate regions and languages. During each maintenance period, everything will be automatically combined for the affected realms. When maintenance is complete, players on affected realms will log into Battle for Azeroth and find that they’re now part of a larger connected-realm community. At the same time, we’ll merge the appropriate realm discussion forums.

Please keep an eye out for notifications here as we proceed through this project. Again, we’ll let you know here in advance when realms in this region are about to be connected.

Thank you very much!
