Not exactly. True, Yoshi P did point out the success of WoW as something to aim for, and had developers play the game to get a feel for what might have led to that success. FFXIV is still a Japanese MMORPG, and utilizes different code and assets - many of them brought from 1.0. The battle system is different, the glamour system was built long before WoW started using 'collections'.
This game is story driven, with the Warrior of Light (us) in the center of things. When someone like Emet-Selch dies, WE are responsible -- unlike WoW, where story doesn't matter, we aren't the main character and every. single. major. enemy. is killed by long-standing characters who are not us (Can you tell that I am still bitter about Garosh's death ... and don't get me started on the Redemption Arc for Sylvanus "I burned down Teldrassil and enjoyed every minute of it".)
Despite the '[lack of] more capable coders', this game still manages to pump out content at 3 month intervals during an expansion (pandemic schedule aside). The charge of '[lack of] software engineering foresight' is pretty funny considering that Blizzard wasn't handing out information to competitors on what and when, exactly, they were releasing new features. The polish you see in Blizzard might just be due to the fact that the company wasn't trying to recover from a major downturn with a failed game that they were trying to resurrect on a shoestring budget.
I would argue that the game you appear to think a piece of brilliant software engineering is still stuck in the 'grind is good, they'll stick with us despite our 9-month content drought' mindset that is so endearing to those who are now looking for some other MMORPG to call home.
