We will see if him seeing these past events truly will be a key. Maybe at the end he will be nothing but a puppet that is over his head and believes he somehow can control an elder primal like Zodiark. After all when Ishikawa was asked who her favorite character is she mentioned Fandaniel [...]. Maybe she meant Fandaniel, maybe she meant someone near him.
Then we have very different views on what counts as a attack. Also your follow with how they dont pay much attention to the lore is also just oof. (If those are all not attacks then honestly there was nothing rude at all about the other poster too.) So lets look at it from the perspective of the topic in this thread.
If someone did not like Zenos until know because he was nothing much in their eyes but Endwalker will bring new story points to him and now people might enjoy him more...are they now suddenly slow and someone dont pay attention to the story because they did not like before that? Does that sound fair to you?
What about Fandaniel? If you dont like him now because he is nothing much right now but that changes in the next expansion are the people slow and dont understand or pay attention to the story?
One of my favorite character is Alphinaud. But I would agree with anyone that would state that he was a bit annoying in the beginning of the story. Only later when he learned and grew as a character other people also started to like him. Are those people slow and did not pay attention to the lore? Or could it maybe be that sometimes characters are just not interesting enough in certain states of the story? There will barely be any character that gets introduced and is just perfect and fully developed at that time. Of course one can already like that version but that does not mean that everyone that does not like them that way and only enjoy them after the development are slow and dont know their lore...
The comment that nobody liked them before was bad, I fully agree...but it was stated by one person that does not like the Ascians at all. So your argument that they are just slow does not even match them.
Also curious about the rampant issue of misinformation spreading here on the lore forum. IMO I get the feeling that its not misinformation but mostly just people with different views on something that can be viewed from different perspectives or where we dont even have the whole answer right now. Otherwise I would be very curious about these seemingly huge problems here on the lore forum.
