Blizzard has confirmed in a blog post that completing expansion meta achievements will unlock player housing decor when the Midnight expansion launches.
This applies to the following meta achievements and expansion:
A Farewell to Arms (Battle for Azeroth expansion meta achievement);
Back from the Beyond (Shadowlands expansion meta achievement);
A World Awoken (Dragonflight expansion meta achievement).
Blizzard has yet to showcases what the decor items will look like, but it’s good knowing that you can start working on completing them now. Some of the achievements, especially those tied to Mechagon, heavily rely on RNG and quests being up.
Therefore, now’s the perfect time to get started.
