There's a difference between a zone that fits into the story and a zone that is designed for the story. Zi'tah and Bibiki Bay are good examples of the former. Attowa Chasm and Riverne being of the latter. I'm against the latter while being for the former.
As always, you and I are not going to agree on that. What CoP did is use the tried and true "cluster of zones" that is typical of an expansion with a couple of scraps added to the main continent. Problem is that they created the zones exclusively for the story, and it shows when there is no real reason to be in the Archipelago outside of the CoP missions barring one or two extra things like subligar farming. Even if you were to go back in time and convince Tanaka to not put in the three promyvion requirement, the zones as designed are not inviting. You wouldn't see the kind of shift to the Archipelago as you did when Bibiki Bay opened up, much less the shift to Bafflau Thickets when TAU hit.Otherwise a lot of zones were designed to be unlocked and explored through the story then later on your own (you know, like a FF game tends to do.) Everything in XI was world relevant and story relevant because the lore and storylines fit into the world like a good RPG.
