Let's recap everything we visited in past expansions:
- ARR had us explore a lot of the City States ;
- HW built upon Coerthas and Ishgard, the Sea of Cloud (3 regions), Yafaem Saltmoor, Dravania and Xelphatol ;
- SB added Gyr Abania and a lot of Othard: Kugane, Yanxia, Azim Steppes, Dalmasca and the Burn ;
- ShB had us revisit a different flavour of Eorzea in the form of Norvrandt, but also built upon Ilsabard by adding Gangos and Bozja ;
- Endwalker intoduced Radz At Han, Garlemald, Sharlayan, the Sea of Stars (the moon and Ultima Thule) and a quick peek to the past ;
- Danwtrail seems to bring us a few locations in the entirety of tural, wherever Vana'diel would take place, and space exploration.

I kinda understand what you mean with Endwalker feeling disconnected, but even compared to Heavensward, the different areas don't really feel very linked to each others :
- The Sea of Stars and Sea of Cloud are clear parallels. Loporrits are replaced by Moogles. It's initially out of reach because blocked by an enemy, and while the Sea of Cloud was known to Ishgard, their presence there is minimal ;
- A lot of time is spent in friendly territory (Ishgard if you can call it that lol, and Sharlayan) but we're split with another settlment quite remote from it, Idyllshire which is thematically and culturally very different from Ishgard ;
- Last zone is a remote and normally unreachable place that thematically has almost nothing to do with the rest of the story.

Mind you, this recipe is applied to almost every expansion.


Additionaly, Tural is a whole continent, about the same size as Aldenard and Othard combined. If anything, having only 6 locations to cover all that immense territory feels more disjointed to me than Endwalker ever was, since I knew of all these place in EW beforehand.
The culture, civilization and technology in Solution Nine and say, Yak'Tel seem to be absolutely different. I suppose it's expected, since they're both geographcially and culturally as remote as Garlemald is from Gridania.

What people dislike in Endwalker and Stormblood is that we jump around locations too often. From Sharlayan, to Radz at Han, to Sharlayan, to Ala Mhigo, to Garlemald, to the Moon, to Sharlayan, to Radz At Han... Thing is, it's just the way the story is being told.
If we're going from Yok to Xak constantly, with the quick interruption where we'll have business in Eorzea to get somebody's opinion at some point, it won't be any different.
