I feel same, especially each time I listen to the Piano Collection (ARR-HW-SB music).
We were exploring our beloved Eorzea and then Aldenard and Othard during those expansions following the story, places and threats being in place since the 1.0.
In most of those places, I have felt a sentiment of serenity (visual, music and global ambiance) when exploring them for the first time (and the numerous times after for La Noscea, Black Shroud and Thanalan).
In Shadowbringers, the direction taken was innovative, but not incompatible with what we have. And some side quests (Trials for example) allowed us to still deal with Garlemald.
But in the First, I didn't felt the emotions from before (also my beloved healer enjoyment was gone...), or not in the same amount. I accepted it, it was well driven.
For Endwalker in the other hand...to me, it was cut in two parts, two small expansions that packed many things into one. At the result, it didn't manage to continue and end of the best possible way some stories and plots.
Furthermore, exploring two times Thavnair (a beautiful area I can see with the tribal quest) under two extreme threats, it was not what I expected at first.
I understood, because of the story, the exploration would not be peaceful, but it's a shame.
To me, we should have had a 6.0 with Isalbard focus (Nagxia, Dalmasca, Thavnair, Garlemald, another Garlemald area, and the Moon), and then 7.0 with Past / Space focus.
Like many there, I would have liked to not reconnect with others scions already at 6.1. It's very weird, especially after the goodbye speech at the end of 6.0.
Also, we are supposed to go on new adventures, right ? Can we not just chill here and there in every place we visited since 2.0 instead of already having a new threat showing up at 6.1 ?
I would love to begin 7.0 with no threat at all, having the choice to explore 3 reposing and pretty areas (cut in several parts as La Noscea, Black Shroud and Thanalan) far away with no major scion at our side at the start of the next expansion.
SE, just give me that 2.0 vibe again. It's the perfect time for it, and I want it.
