Random observation

[BRVV]

- An expansion that deals with cosmic threat and concludes a multi-expansion saga, has us flying in a spaceship into another planet/dimension at the end.

I was amazed about what little connection there was from Endwalker to previous plot points.

- An expansion before that dealing with an alternative timeline that has a bait-and-switch moment where the good guys almost won, but then Emet betrays you/Gul'dan subdues the Iron Horde and there is another mini-arc after that

Wasn't Emet in Shadowbringers an Antagonist who actually did help us? Exactly the opposite of what you claim here? Or what do you mean?

- An expansion themed around Asia and focused on a war without an obvious large-scale threat(not front and center at least, both have one in the background)

Stormblood focused on the war and had both the Empire aswell as the typical summons. Zenos, the killer everybody seems to love, was introduced there and the main villian front and center. Idk what you need to qualify a "large-scale threat". Does it always need to be something weird that will only be stopped with the power of friendship?

- An expansion focused on dragons with a furious seething dragon as its primary antagonist(also bonus points for the similarities between shattering/7th calamity)

I'm not into WoW. Do you put Heavensward with that Expansion where a dragon reformed the land or do you mean the upcoming dragonflight? Bonus points for the dragon of FFXIV and the shattering being not at all connected.

Is it poetry rhyming or "borrowing" concepts?
Is Gaius the Lich King?
Are we heading into FFXIV's BfA?

Hell if I know, but the parallels are fun.

“You want to find the number 216 in the world, you will be able to find it everywhere. 216 steps from a mere street corner to your front door. 216 seconds you spend riding on the elevator. When your mind becomes obsessed with anything, you will filter everything else out and find that thing everywhere.” - From the movie "Pi"
