Blizzard are planning to merge some World of Warcraft servers in response to dwindling player numbers.
Obviously this isn’t how they’ve chosen to word the news, instead labelling the feature of Patch 5.4 “Connected Realms” on their blog.
“Building on our existing cross-realm technology, a Connected Realm is a set of two or more standard realms that have been permanently and seamless “linked.”” reads their description.
“These linked realms will behave as if they were one cohesive realm, meaning you’ll be able to join the same guilds, access a single Auction House, run the same Raids and Dungeons, and join other adventurers to complete quests.”
To de-BS that simply replace realm with server.
World of Warcraft’s population has been on the decline for three years now, falling approximately 12 million in late 2011 to around 7.7 million earlier this year.
The data is presented in this handy graph.
