Back from finishing 7.3, it's hard to ignore the importance of the remaining shards in the state of the story. But I guess we still have to get a better picture from the villains' plans to better imagine what the stakes are.

If anything, I can say what I do not want, and that is anything cosmic-sized. Endwalker did it, it was kinda odd for me, I'm fine with other planets being side-story content like cosmic explorations.
I also think there are places on Aetherys which should keep some sort of mystery aura until the story can fully commit to them. Sorry for the persecution on EW, but I feel that the six zones ended up being underdeveloped by being crammed into one expansion when Thavnair and Garlemald deserved more time, and the Ancient's world bleeding into the end of the universe could have benefited from more time too. So if we finally get to say Meracydia, I hope for some very focused writing on its own story.

(And I absolutely would NOT mind a far shorter MSQ than EW and DT for 8.0 actually. I'm also fine with the expansion focusing on 2 or 3 scions, leaving the others for a while. And allocate that extra questing time to new job quests for instance)
