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

[Lauront]

Can I also mention how utterly lazy it is that we technically fought Hermes/Fandaniel three times in Endwalker?

1. Fandaniel piloting Zodiark.
2. Hermes in Ktisis.
3. Amon in the Atiascope.

Did the devs run out of ideas for bosses?

I think they ran out of ideas from the minute we encountered Fandaniel. Seems like they wanted someone to kickstart the apocalypse and kind of make you think the ancients are 'scary' if you squint (only Elpis and Amaurot sidequests pour cold water on it) so that Venat was not cast in an antagonistic light. Whether this was the original intent or the result of squashing the plotline, I don't know, but other than brief clown moments in SHB and EW, I can't think of much I enjoyed about him.

Not so much an issue as a mitigating factor that IMO absolutely should be brought up whenever Omega's lines are referenced: Omega was a person, now machine, that lived in a constantly at-war culture and a survival-of-the-fittest hellscape, whose very design is to constantly evolve. I'm not exactly surprised then it would come up with "ackshually Hermes good because brutality results in evolution".

I believe they were using it as a further way to allow you cast doubt on Venat's reasoning, because the premise Omega is working with when he asks that is inherited from her own approach.
