Yes, I'm aware of the history of the franchise, that's why I specifically said Square-Enix not just Square. The company need to change, they have been an example of culeless-ness and mismanagement during last gen. that why I'm pleased to see key people like Nomura making a bold move like this to explore new possibilities.

Sakaguchi hasn't really been able to work with his own formula better than SE has since he left either...
just saying.

Lost Odyssey was the exception.

Hum... When he worked with his own formula, he did it better or at least morein line with the expectations of the fans. Blue Dragon, and especially Lost Odyssey are two great examples of that. What more, they're the only two examples from his using this classic formula. 

After that, he made The Last Story and tried to re-invent himself from a JRPG gameplay point of view.

I don't consider Blue Dragon particularly Good... Nor is it particularly more successful Metacritic (User or Critics)  FF dimensions, and definetly worse recieved than Bravely Default (though SE only did the music and art design I believe). Hence he used his formula better once, was my arguement. (But admittedly he only tried 3 times, SE tried a lot more).

While Last Story definetely was not traditional in any way. (FF had more success not being traditional with FFXIV and FFType-0, though it had the unfair advantage of FF, and SE as a whole had a whole lot of successful non traditional games).

My main feeling/argument is that they both weren't that good last generation, but Sakaguchi gets credit for being a savior or amazing by some when imo he wasn't. 

Blue Dragon was awful though. The Last Story was good, and I absolutely loved Lost Odyssey. I don't anyone liked anything about Blue Dragon except for it's battle system and boss battle music.
