What small QoL changes could they make to improve the experience, in your opinion?
The thing that came to mind for me is allowing the use of the ferries to/from Limsa earlier- after your level 10 class quest is completed.
It doesn’t make a lot of sense to keep just Limsa Lominsa closed off when Thanalan and the Shroud have a land route between them- with no restrictions but being smart and not aggroing any mobs.
It would help Limsa players who are picking up ARM/BSM to be able to mine their own ore. All classes would benefit from CUL, and FSH is usable globally.
In general, freedom of movement is a good thing for this game.
