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

[Wildheaven182]

• The mighty Zodiark, which has been build up as this mighty(evil) entity over several expansions, turns out to be nothing but filler trash for the first Endwalker trial
• The true cause of the Final Days is a pet-project from an ancient which goes mad after observing countless dead world and possibly causing the death of several world by projecting negative emotions unto them, and is thus dead-set on bringing despair to every world, upon which said ancient goes mad and is now letting her run her course to test humanity if they can withstand/fight despair
• Venat, who hasn't had her memory wiped + still remembers you from being in Elpis, quite apparently doesn't lift a finger to learn about Dynamis herself or to mobilize the other ancients to end Meteion then and there, and instead chooses to turn herself into Hydaelyn, sunder the world and the inhabitants, thereby forcing them to live with and face despair and gambling that their resilience against despair might be enough to face Meteion one day

Really?
This is the best SQ could do in terms of story after ShB?

Well hey, the devs spent a lot of money developing the world in Elpis, the devroom. But some of the ancient developers didn't have their ideas implemented or their creatures were not approved and so were trashed. The developer Hermes couldn't stand treating their creations so flippantly. And then the players didn't even like the 1.0 game. He looked to other games and saw many which also failed and flopped.
The devs split over the 1.0 world, those who wanted to maintain it and couldn't accept its failure, and our lord and savior Venat-p who made the ultimate sacrifice to bring about a realm reborn. Many of the original devs were purged, but some of those who remained still harbored feelings of resentment and a desire to bring back 1.0- the Ascians.

Also yeah if you thought the primals were anything more than a pile of aether, hydaelin and zodiark and even the 12 were also just a pile of aether but with a person as a dumpster.
