Further MSQ thoughts:
Although I stand by my previous comments in regards to thinking that some parts were rushed and other parts a bit convoluted, I consider the portions that take place in Garlemald, Thavnair, Radz-at-Han and Elpis to be some of the best MSQ content in the game to date. I'll need further time to sink my teeth into the side quests, since there's a lot of them.
Between the Reaper storyline and the Garlemald MSQ's, I'm pleased to see that the nuance was handled well and that it was made clear that Garleans have been fighting for survival for quite some time now. I'm curious to see if the Garleans retreat from the frozen wasteland and settle in their original homeland given how frequently it was brought up and name dropped.
I think a genuine effort was made to squeeze as much fan service in as possible for every character brought up even in passing. I can appreciate that and I'm glad that some of the side characters who might have otherwise have been 'one and done' characters showed up again. Sicard being one of the more prominent examples to my liking.
I appreciated the body horror for the monster transformations. I hope we get more stuff along those lines in the future.
As I thought, we're also moving towards seeing our character become an adventurer again. That pleases me and it makes sense given that we have a largely clean slate to work with now. I imagine we'll still see much of Endwalker spent on wrapping up the plot threads established within the expansion itself as well as building up the groundwork for whatever the new storyline happens to be.
Although I would have liked to have seen Hydaelyn and Zodiark team up against the cause of the Final Days and potentially stick around after that fact, I'm glad that they're both gone - having one linger but not the other would not have felt right to me and with the Sundering being revealed as a deliberate act and not an accident, I could not help but see her as an abusive, if well meaning mother figure.
Though as Yoshi-P said, it's a complex situation and a matter of perspective so a lot of people are going to have varied thoughts on pretty much every major event that occurred during Endwalker.
Overall, Labyrinthos ended up being the weakest link for me. It wasn't terrible, though the first portion didn't grip me as much as the first trip to Thavnair did and the second visit to Labyrinthos had a bit too much padding for my liking. Visually, though, the zone is very pleasing. Old Sharlayan, too, is a beautiful city.
