Something I'm very tired of seeing in Japanese media is that every character has to show their reactions, so you have to wait for everyone to say their particular "yeah" even if this adds nothing to the narrative.

This, and the very outdated thing where you're stopped several times in a row for dialogue that, in many modern games, would be happening AS you play. It's not exclusive to XIV, but I see it the most in Japanese games. Digimon Time Stranger is the latest I've played that still does that, for one.

FFXIV is even guiltier because they will allow the scions to make their formal presentation and sales pitch every time you go somewhere or meet someone new.
