Itโs not often that a World of Warcraft expansion includes a feature so seismic to the 21-year-old massively multiplayer game that it gets top billing โ above the storyline, the new questing zones, the raids, the other new gameplay systems and updates, everything. Itโs not often that the feature gets revealed separately and even launched separately, coming out three months before the expansion release date and six weeks before the pre-patch that will add all the other tweaks and features that arenโt specific to the new content.
