I find it completely sad. (Questing)

So, your pretty much saying. The "best" way to learn about the game, is not playing the game?

No
the way to learn about the lore (i think you mean lore, not game play) is to read everything in the game. Even what a random NPC have to say.
Then put the pieces together to get the whole pictures.

But because memory can be tricky, it help to discuss with other to refresh the memory or to get other lore pieces you overlooked.

If you want to learn about the story in the game, stop skipping NPC dialogues.

The story in Final Fantasy XIV is pretty weak compared to other entries in the series
"Go and deliver wine so you can go and fight Titan Adventurer" - Bravo Lucas!
4 levels of this boredom and you forget why you're doing it because you wanna get it over with I love that shit in my Final Fantasy games.

Heavensward I can remember since it had less filler stuff that goes over your head.

You learn alot about Bachus wine and how its grapevine was belived to be extincted since the calamity.
You also learn the people in wine port.
