I stopped caring about WoW's zone design when it began actively destroying large swathes of interesting territory and replacing it with sub-par content. The original Redridge was very charming...but ended up being replaced by obnoxious movie references. Uldum was hyped for years as a great mystery...and then ended up being another tacky movie reference that overshadowed the more unique, interesting stuff. Memorable zones such as Ashenvale and Theramore were also desecrated for the sake of pushing an increasingly contrived faction conflict that is fated to always be a stalemate.
FFXIV, for me, wins in terms of gear design, environment design, story and music. I even prefer FFXIV's combat since it just feels so much smoother and visually satisfying. I do vastly prefer some of WoW's playable races, though. I was always a fan of the blood elves and their struggle for survival. FFXIV's playable races feel too 'human'. Even those with unique cultures end up being changed to fit the 'every1 must be fwends or die' agenda that is common in JRPG's.
I want the Xaela to be seen as wild and scary. I want to see less 'City Miqo'te' and more Tribal Miqo'te. I want the Raen to...have an actual presence beyond a couple of minor NPC's and a secluded settlement hidden beneath the ocean. WoW isn't perfect in regards to racial lore but throughout the expansions I knew I could consistently count on getting new blood elf settlements and lore.
In FFXIV, that's something that is sorely missing. Duskwight Elezen and Raen Au Ra are arguably the ones that drew the short straw.
