Back in the 1.X Version(s) of the game, the world was 1 huge area, without "real" loading screens. In later 1.X versions, the game's major cities were divided into separate areas via loading-screens. This was mainly because of the PS3.
This problem still exists today and is especially apperant in Limsa Lominsa, with it's upper decks.
Since the PS3 is no longer a supported and with the PS5 now released - it is time we ask for "uninterrupted" cities (or even a whole game-world) - just like in the old days.
And what would be a better time to ask for major improvements like this, than the "final" expansion of this game('s current story)?!
Endwalker should not only be the end of the currently ongoing story - it should also be the end of FF14 as we know it - in purely technological terms, of course.
