That was the case for old players too. Back in the old days it was like:
Players: “So, what’s going on with the king of Stormwind? Why is he missing? There’s this quest chain we’re getting that just kind of randomly ends and has no resolution and we don’t find him.”
Blizzard: “Just wait, we’ll release a comic book about it eventually. He’s doing like SO much, he got split into two, one half’s doing like Arena stuff with the Horde, the other half is actually ruling Stormwind again but he’s bad at it, and Onyxia is manipulating him, and she kidnapped Anduin, but then his other half came back and they merged somehow during the fight because Onyxia deep breaths more, making their swords merge too, then he cuts off her head and gets praised for taking out the black dragon.”
Players: “Wait, didn’t WE do that big Onyxia quest chain? I thought it was a raid of players that did it, after we revealed her to Bolvar.”
Blizzard: “Those quests didn’t count, that’s not the story. Varian did it all. Just buy the comic book.”
