Yesterday, Blizzard announced that World of Warcraft will receive patch 9.2.5 next Tuesday. The update includes a highly requested feature: cross-faction play. The 17-years-old MMORPG never allowed Alliance and Horde players to group up, but now that's going to change.
Here's an official overview of how cross-faction play works in World of Warcraft and where it is not allowed.
Players will have the ability to find Premade Groups in the Group Finder for dungeons (Normal, Heroic, Mythic, and Mythic+), raids, rated arena/RBGs, and also Torghast. However, the group leader may restrict the listing to same-faction applicants if they choose.
Once in a party, members of the opposite faction will remain unfriendly while outside of instances, though they will be able to communicate through party and raid chat, as well as use /say and /yell within proximity of one another.
Upon entering a dungeon, raid, or rated PvP match, however, all members will be friendly and able to assist each other in combat, trade loot, earn shared achievements, and otherwise fully engage the same way members of the same faction do.
