I really liked Stormblood in many aspects, but one in specific, I think it was extremely flawed and is the 'double feature' aspect of that expansion's story by dividing the zones equally, because it leaves a want to see more of each end. Regardless, they could have tailored the story in a way that Ala Mhigo became the secondary capital (Radz-at-Han equivalent) instead of Rhalgr's Reach.

Maybe they could have fleshed out the Gyr Abanian zones a little better, because even though it's made up of 3 zones, I feel that it's just a big single one. I know the geography of that area is mostly the same, so there's not a lot to do with that, but maybe the story could work just with the Fringes and the Lochs, leaving another zone to be added to the Othard front - maybe a little more of Hingashi, the smaller island that Kugane is at.
