For the first time in World of Warcraft's history, Horde and Alliance players will be able to join the same guild

pcgamer.com:

Blizzard has revealed the release date for one upcoming World of Warcraft patch and shared details for another, the latter of which will add a much-requested cross-faction feature, allowing Horde and Alliance players to unite under the same guild banner for the first time in Azeroth's history. 

Last year, a minor Shadowlands patch started to blur the lines of the faction divide(opens in new tab), allowing players from opposing sides to team up for certain types of group content. The update also gave in-game communities the ability to turn on cross-faction functionality. Guilds were still fully locked down, but that's set to change with the newly announced(opens in new tab) Embers of Neltharion update.

World of Warcraft was built on the conflict between Horde and Alliance, and while many of the expansions' storylines have seen them come together and temporarily put aside their differences for the greater good, the opposing factions have always been very separate when it comes to actual gameplay.

«We are trying to be really considerate with [cross-faction] changes and, you know, watching where we step as we make changes because we recognize the impact that that has on, not just our community, but the game itself,» says associate game director, Morgan Day, in an interview with Wowhead(opens in new tab). «Factions, Alliance and Horde, are a huge part of World of Warcraft. Even if I can play with people on the other faction, the tremendous weight that they have [...] in the story is something that will never go away in World of Warcraft.»

There are no real details of what cross-faction guilds will look like, or if any restrictions will be in place. Still, it's certainly exciting news and blows the possibilities wide open when
