Endwalker Story sucked and it's time to admit it

[Iscah]

Firstly.
If the WoL is dead, they can't go to Elpis. Can we agree on this?

Secondly.
If the WoL doesn't go to Elpis. The sundering still happens.

First statement, yes. I have never claimed otherwise.

Second statement, irrelevant to my argument.

There is no version of Elpis where our WoL doesn't go there.

There is no separate version of Elpis waiting for the 8UE WoL to arrive.

If the 8UE and Endwalker timelines are branches, Elpis is on the trunk of the tree. It happens once.

An observer from the 8UE timeline branch cannot detect the Endwalker timeline branch, but they still both exist next to each other and have always existed alongside each other, because G'raha split the timeline in Shadowbringers. There was no period where the timeline only had one branch and was waiting for the other to materialise.

The 8UE timeline does not need to reach the point where the time machine is invented before its effects are felt.

The paradox only exists on your parallel lines, which I disagree with.
