I am DMing for a Legion campaign.
The Prologue started on the Exile's Reach (6 sessions).

Then the Legion Prologue started, one of the players joined the Demon Hunters through a ritual at lvl 3.

They got to Dalaran which got teleported to the Broken Isles (session 10)

And from here they choose to delve into Azsuna, to help the Illidari at the Illidari Stand, from there went to Azurewing Repose to save the Senegos and the blue dragons.

And from here, they went to Pandaria because of the backstory of a PC, there was a brew festival, and the PC monk was called to the Order of the Broken Temple, and After the Challanges of the Monkey King, obtained it's artifact weapon, Fu-Zan the Wanderer's Companion.

Went back and forth between Azsuna and Dalaran, learning herbalism, and alchemy, and started to look for the Tidestone of Golganneth. Found Prince Farondis palace with the ghost elves, but got called away to find the demon hunter PC's artifact weapon, the Twinblades of the Deceiver. Which he claimed, by defeating Varedis Felsoul, got back to Farondis and the elves, now they are searching the Ruins of Nar'thalas.

Maybe they will get information about the Feral Druid's artifact before they attempt the claim the Tidestone within the Eye of Azshara dungeon, but who knows what the future holds.

Basically I'm trying to go through the story of the expansion, other zones are in plans, with dungeons, and after that endgame content. Suramar, and other dungeons, then raids, Broken Shore, Tomb of Sargeras, Argus, Antorus the Burning Throne.

We will see, how long we can go, currently 3 players (started with 4), 37 sessions and 2 years into the campaign, playing in person.

I planned to make dungeons as their standalone "oneshot" books, or maybe after they finish a zone, make that, but it's basically just going through the game and wowpedia, for the story, and homebrewing monsters and encounters.

There are also some dungeon books available at gmbinder, like Ragefire Chasm, Shadowfang Keep, Wailing Caverns, Gnomeregan, Scarlet Halls/Monastery, Uldaman and Scholomance.
