ZZZ story is a lot simpler and thankfully isn't as wordy - tangent rambling like Genshin and HSR can be. I guess MHY wanting ZZZ as popular/success as Genshin and HSR in someway. Considering mobile revenue during 1.2 not doing great (Sons of Calydon patch), they were probably in "panic" mode. So Idk, whether the whole urban design and biker style aren't that much well-received for China. Despite Caesar is pretty top tier and Burnice is also quite good. Tbf, none of limited 5* ZZZ has been released are bad. All of them are solid to very good strength wise. Miyabi is just intentionally broken in many ways.
This patch works as a soft-relaunch. TV wasn't perfect, it did improve, but at the same time they remove few unique and "soulful" design of the game. The weekly rogue-like game mode Hollow Zero, it has rng of collecting these items to do "hidden" side quests. Imo, they add neat world-building and side story telling.

Collecting all items from that Hollow Proposal keep you wondering whether the guy and the girl in audio record make it out of hollow zone and marry to each other. But playing the quest, it'll show you not only the girl is actually a police officer patrolling on street where you live. Both of them even have a daughter now.
Some have sweet ending. some ends on a more "thank you for your telling me" tone. It's just that, the rng to trigger event to collect these items can be quite annoying. TV mode is "no more" and Withered Domain won't have anymore updates. No more these kind of side quests. Even the Mewmew officer mascot won't get update again, the guy don't even have any audio voiceline when you talk to him this patch. All of these things give players incentive to interact with small hubs and npc for world building, this patch is the last of them.
Character story quest wise, it's still 50/50 MHY writing whether focusing on characters more or NPC more. But this patch, Harumasa one is pretty good imo. It hits all the tropes that would make husbandos collectors happy. He shares some similarities to Scaramouche, even more so in JP. Even with the add "quality time spending" dating thing, it feels leaning more into you-the player is special to gacha characters at the end.
Combat wise, I'd say it has the most (out of MHY games) letting you optimize rotation more. Whether you do full chain attack for x2 or x3 multiplier for decibels (character ult meter), or you cut short since your dps character can finish off remaining of boss health bar. What I'm not really into the new Decibels change yet.
Before everyone sharing one Decibels meter, only main DPS character will do the ult. Now everyone has their own Decibels meter, so MHY give enemies more HP to compensate. So ATK dps can feel bad when using their ult isn't doing as much total % damage to healthbar as they used to be. Anomaly bar build up, stun duration & build up are still the same.
Here is the thing, the timer count down for the ranking in endgame stops during ult cinematic cutscene but stun bar still goes down. Basically for typical, Attacker - Stun team, they have to slot in Support ult in that stun duration (does damage and gives Energy regen for team) too. It's getting harder to get more value for Attacker-stun team. Meanwhile Anomaly-disorder team doesn't change much, it doesn't help game still having bunch of buffs for anomaly dps.
Then also considering, they starts adding more multiple elite enemies for later floors. You have pay more attention in doing damage to both at the same time.
It just happens Miyabi herself is broken not only in numbers, but also in her general mechanic gameplay. She does lots of damage, big damage move has "entire room" AOE size and also very easy to play - innate big iframes for big damage move. She's so far up to any other dps even without her signature. Difference between her sig and her best F2P is 30-40%. Not only that, majority of enemies in this game are Ethereals, most of them are weak to ice. Miyabi is ice with her unique Frostburn mechanic.
I'm just being foolish stubborn on not rolling her.
Maybe Skirk will have a similar Frostburn mechanic to Miyabi, but can also be similar to Arle's pyro dot in her E.skill.
