Blizzard has announced that cross-faction dungeons, raids and PvP are coming in Patch 9.2.5! Summary:
Guilds will remain single-faction. Random matchmade activities, will also remain same faction. All raids, dungeons and rated PvP will be cross faction, barring some exception raids with faction specific components (e.g.Battle of Dazar'alor, Icecrown Citadel). Group Finder will be cross-faction, however the group leader may choose to restrict to same faction if they wish. You can directly invite members of the opposite faction to a party with BattleTag or if you're part of a cross-faction WoW community.
For years now, many players have questioned whether the rules restricting communication and cooperation between Alliance and Horde need to be so absolute. The faction divide could keep close friends from playing together, or cause players to feel that their faction leaves them with far fewer opportunities to pursue their favorite group content. But these downsides have long been justified in order to preserve a central element of the Warcraft universe—it all began with a game titled, “Warcraft: Orcs & Humans,” right?But, to quote a one-time Warchief of the Horde, “Times change.”I am pleased to announce that we are working on adding the ability for Alliance and Horde players to form premade parties together for dungeons, raids, and rated PvP.
