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

Where is it canonically stated that a paradox is created when you time travel within the universe of Final Fantasy XIV?

It isn't. I've already said that several times by excessively referring to my ideas as opinions. The devs haven't confirmed or denied but rather offered "maybes" and "form your own opinion on it". So that's what I did. And I'm not the only one...it is a very common idea.

But it's equally as common to take the WoL being in Elpis very literally when it really doesn't make any sense and creates all kinds of uncessary problems. I think you guys just like to complain personally.

And it defies reasoning in a way bc why then is Venat retelling us the entire sundering experience as though we don't know...the answer is..bc she isn't. Once we left her tineline our experience with her simply conjoined with the present day. The sundering abstraction we saw is the original sundering of a non aware Venat, obviously.
