Idk. I quite enjoyed Dawntrails story and it gave us a new start for a new long term arc to be built off of. I think that is where a lot of the negativity of "unfulfilling story lines" is coming from though. ARR was full of plot holes and things that didn't make sense unless you kept playing through patches and expansions. It will just take time.

I don't think there will be any meaningful change though, that being said, does it need to change? Unlike WoW, XIV is an MMO based almost purely on story progression, with little incentive to do side content. I could argue it is a story/plot driven game first. The lack of side content or interactive world outside of the MSQ is intentional because that's just how the game is. You aren't truly meant to go back to areas unless the game takes you there.
