The DRK questchain I enjoyed, as it was an interesting psychological take on the trauma the whole MMO was on our otherwise "silent protagonist". If Ishikawa was responsible for Ysayle, Ysayle's arc was my favorite thing about Heavensward, even if they did have to retcon that opening scene of her attacking Ishgard directly. (Moogles were "so fluffy", so that may have indeed been her writing.)
But I haven't had confidence in either Ishikawa or Yoshida since Stormblood, which seemed so much more concerned about the colonizers rather than the colonized, and while Doma was thoroughly explored, Ala Mhigo seemed just a rushed prop to make Yda--er, Lyse relevant in some way, killing every experienced officer in line to command until it somehow fell into her lap because of her name. (They brought back Meffrid only for a shock killing, that lost me extra.)
It also highlighted an odd narrative style that feels very much like certain characters were being shoved in your face, the writers saying "Do you like this character yet? How about now? Now? HOW ABOUT NOW?" It was Lyse and Fordola, then. Gaius got that treatment in Werlyt later.
It only got worse with Shadowbringers, which relied on despicable stereotypes for half of the story arc, and the trailer made sure their intent to show "fat is lazy/evil" was on full display. If I had a nickel for each person who didn't know Dulia-Chai was the Stoneworks bookkeeper because all they had her talk about is cakes, I'd be rich--and the hypocrisy of Alphinaud's judgements on Eulmore versus our buddies, the Allied city-states, was unreal.
The nobles of Ishgard, not lifting a finger to invite in the shivering poor of the Brume? Our besties. The Crystarium, stating if we expected to stay, we'd be expected to work? Our besties. Doma, using the Xaela tribes as meat puppets for a war otherwise not their own, and quietly hushing over sex traffickers? Our besties.
Eulmore, not letting in "the hopefuls", who left their homes and farms and families for a lotto's chance at something they were never promised, and self-inflicted squalor? Eulmore, the place that provides bouncers to protect dancers, the place that paid workers so well they were unhappy when it switched to capitalism in 5.1? The height of evil. "Bones of the poor", even though only the free citizens were guaranteed "Ascension". The evil rich, even though rich people were made to give up their wealth to get into Eulmore in the first place--in order to make everything free for all living there, including workers, who outnumbered the free citizen by far. (Sure, a lot didn't like that and left immediately in 5.1, but they weren't getting in before that otherwise.) And as soon as we learned Eulmore was the main fighting force against the Sin Eaters for 80 years until all the loss broke them, the writers promptly forgot it again to condemn them as a "perverted paradise" (which bought all their produce from outside settlements). Funny, anguish over loss was a perfectly acceptable excuse for Emet-Selch.
This doesn't even cover the DBZ-grade character that is Ran'jit.
And then there's Vauthry, Ishikawa's take on Yoshida's request that the last-minute midboss be "Jabba The Hutt". The narrative had so much worse to say about that character than the one who made him, in utero. There was never a believable chance for that character to be anything else by the game's own lore, because even the WoL can't fight a Lightwarden's corruption, let alone a baby groomed from birth to do the Ascians' bidding. The "truth" about the Ancients was of paramount importance, but the truth of what happened to Vauthry was never told. In fact, the dialogue options in 5.1 let us blame him for the misdeeds of the free citizens, even though Alphinaud previously preached taking responsibility for your own actions.
As excited as a bunch of people were at the prospect of the "thicc'qote" rig, in the end they were only made to push those lazy tropes. We will likely never see those rigs used again. This attitude tracked clear back to Fanfest 2014, where a cosplayer tried to give Yoshida one of their props only to be told "real ninjas should lose weight/work out more" in front of thousands of people. Imagine doing that to someone who loved your game so much they made a cosplay and paid to be at your convention. (And when they placed third in the cosplay contest, many of this "great community" said it was out of pity.)
Endwalker, I'd be disappointed in equally, as it made just about as much sense with even a little critical thought--if I were supposed to pay attention to the story. According to Yoshida, that's not the case. Just stop thinking about things, and give $quare your money--which I guess is the best he could say, given the absolute mess of a story Endwalker proved to be.
