Naoki Yoshida's Comment in Regard to Jump Potions/Boost Potions

[Felis]

Still can't fathom why someone would want to pay $70+ for a game plus sub fees and then skip over 2/3rds of it just to play (and likely be kicked for not being very good at) the first 4 or so endgame progression raids they eventually put into 4.x.

You seem to speak about the level up potion

Whereas if they insist people have to complete two expansions worth of content, plenty of new players won't try the game at all. Arguably the biggest complaint amongst people who either lost interest or are turned off from trying to begin with is the gated story requirements.

You seem to speak about the story potion

Story potion and level up potion will be seperate

So yet again, the better solution would have been to put effort until uncoupling the MSQ from all the game features so that players can complete it at their own pace.

Without the required MSQ, having to level 1-60 to access Stormblood would be pretty standard. I can't really imagine many people complaining about it.

That would require rewritting the whole story (Ishgard would have been never closed and no Garlean borderline between Eorzea and the occupied area).
The stories of 2.0-4.0 are connected, not stand alone stories.
