What's the point with that quite lackluster story in Endwalker?

[Absimiliard]

While the parts about the Convocation are 99% the same (Hythlodaeus does seem to say something a little different in the last line: "What you have to say too, I strongly think they will come to accept"), the line about Venat's robes I had to look up a bit, to find out what that kanji in the bracket meant (it means "dyed"/"printed"). The two lines overall say: "The white robes fastened by Venat are, proof of a just person, without [dye]' (which I'm supposing is what's used as "untainted" in the translation).

That would be correct. However, one important detail missing from EN (but seemingly present in other versions) is just how these advisory postions relate to Elidibius. The EN text does touch on it, but it does not convey the context properly at all.

In any case, it was brought to my attention the English text actually does mention the position being available also to those that did not serve as members of the Convocation, which makes the entire point I was making moot. :P Apparently, part of my argument has been against people's headcanon instead of what's actually in the game. S'what I get for assuming people are arguing in good faith, I guess. Pretty easy assumption to make given how much of the game actually is inaccurately translated, whether intentionally or not.
