Old school fans of World of Warcraft, that started playing the game during the Vanilla version of the game have made a petition that managed to gather 240.000 unique signatures with the whole intention to show Blizzard that they need to create official Vanilla game servers, since they have shut down the private Vanilla server called Nostalrius. Blizzard officially announced that Legacy servers will be coming soon enough.
They should have enough motivation to create the Legacy servers, since there were almost one million of accounts created on the private Legacy server, Nostalrius, and it had a population of five thousand to eight thousand players on the PVP servers, and around three thousand players online at all time on the PVE server, and these stats actually looked better than the population of the official World of Warcraft servers had before the Legion update. And this Legacy server addition will bring them a lot of profit considering that 240.000 people signed on the petition, and if at least half of them renewed their World of Warcraft subscription, they will revive the World of Warcraft community.
Blizzard said that first they need to re-create the server code since they do not have it anymore, and that the materialization of the Legacy servers will take some time. People are expecting that the official release date for Legacy servers will be announced at the BlizzCon in Anaheim, California 2016, but unfortunately that is not going to happen.
The Production Designer and Vice President of Blizzard J. Allen Brack, has stated that the Blizzard developement team is still in the project of discussing if they should release the Legacy servers. He also said that the release of the Legion patch is their main focus at the moment, and that the story is just beginning, and this is all they are going to talk about at the upcoming BlizzCon event.
