Tales of Adventure - when will these get updated for Endwalker?

[Seera1024]

I would actually advise you to tell your friend to play through the story and level naturally.

They'll be lost when they get to the story in Endwalker. They won't know who is who and what's so bad about the villains we're up against.

Also they'll be at a higher risk of information overload from the skips and their skill at the game will be affected as they've not been introduced to systems and skills systematically as they leveled.

FFXIV to me is more about the journey than it is about what you do at end game.

If your friend is wanting to play with you, I'd suggest making an alt to level alongside them. Choose a class that starts in the same city if not the same class.
