This tier was completed with less oversight than usual; Yoshida stated in an interview that he didn't actually finish his typical checks of the raids.

I sympathize with YoshiP, as he's in a position where he's viewed as the 'savior' of Final Fantasy, and as a result his entire career is essentially staked on the success of FF16. Thus, he's been spending a lot of focus on that game, as well as moving the attention of trusted talent to it as well. This is pure speculation, but I think this raid tier is another 'b-team' tier like Edens Verse, where the lack of experience of the developers working on it is apparent.

The notion that the balance team got 'too good' at the fights is pretty funny, as there is no amount of 'too good' that could feasibly make certain team compositions clear doorboss consistently/easily in 610 gear. All that statement has done is give more ammunition to the weird non-raiders that have been going around mocking people who are struggling with p8s. I can't even count the amount of times someone tried to imply I was simply bad at the game over the last two weeks, and it's really demoralizing on top of the state of my job.
