Emet listed like 6 things we are completely clueless about that each could be there own expansions ESPECIALLY including the other world stuff. Did people forget their is a literal world of void and cosmic horror that has been chilling there since ARR.

No Hydaelyn or Aether shield from Zodiark and I can tell you who is coming for dinner very soon. All that is going on now is the story is not about chasing Ascians or rejoinings anymore. It gives them far more freedom to not get caught in a repetitive pattern.

Rift another MMO got caught in a very predictable pattern where the expansions looked amazing but it was insanely predictable.
