They might still have to do something about it eventually, guess we'll see next expansion. Story skip is nice but means you have to make an alt if you later decide to see the story which is a bit dumb. A lot of people when a new expansion releases just want to play that new content first, and then once they're bored go back and do older stuff but XIV does force you to do everything sequentially. Doesn't help that the quality of the original work is pretty garbage.
In general they probably need to work on the low level experience overall. The combat is boring as fuck since they gutted a lot of the lower abilities, a lot of which were oGCDs, the story is meh, it involves a stupid amount of running, Castrum is still one of the most stupid designed dungeon ever and leveling isn't really that fast on the first char unless you have the new 100% xp bonus thing. I think an additional boost to xp the first time around(maybe just apply armory bonus to first char up to 50), a massive culling of the 2.0 MSQ shit and the 2.1-2.4 shit, removing a lot of the MSQ locks on features(not all, some made sense like chocobo or whatever, but some are pretty dumb), reworking Castrum to be solo, reworking the classes again to make stuff available earlier(you shouldn't go 20levels without getting a new skill like Bard and such) and the ability to skip expansions after that. Like if you hit 60, you can stop doing HW stuff and head to SB. Can come back later. Maybe have a warning to unlock the first SB quest like "warning, starting this questline might contain spoilers from previous content etc etc".
The story skip potions would still be there for people who just want to unlock all content at once, but they wouldn't be necessary(although arguably this might not happen since that would reduce the amount of story skip pot they sell).
Maybe won't happen next expansion but the one after for sure. It's kinda like how WoW had to redo a lot of shit with Cataclysm because it was so outdated. It sucks having to divert ressources from new shit into old content but the new player experience is vital for the longevity of a mmo, if people quit before they reach endgame, then they're probably never coming back.
