Think any of this could/would/should be used in Shadowlands.
With the infinite realms of the Shadowlands, and the Purpose, and the Eternal Travelers.
We have to go to different realms and stop the Maw Covenant or others from taking over.
Make proper and fun and fulfilling use of Island Expeditions. Gather anima, but at a much much slower and more deliberate pace. Some fun exploration, less fast grind.
Maybe see some old faces we havent seen in awhile, like Adm. Taylor or Runas or maybe the missing Blood Princes. Dranosh, VanCleef, Deathwing, Zuni, Cairne.
