The first thing I would do would probably be improve combat.

1. Fix the bugs wherein you can't properly perform attacks.

Unless its been fixed very recently, certain characters like Mona can't preform charged -> charged attacks properly, but can perform charged -> normal attacks properly. Klee also suffers from this problem. Thus, routinely players may click a mouse button and have no actions occur. IMO, this is the biggest bug in the game due to how constant it is.

2. Removed the added in delay that prevents quick character swapping & immedate skill usage. If a player is too fast, instead of anything occurring one hears a beep and then the character does nothing, ruining rotations.

3. Fix character swapping. Its annoying to press the swap key, and then use a skill or a burst, only to have the character not swap & use their skill or burst instead of the character one was supposed to have swapped to.

Toggles to auto-aim and auto-climbing.

Its rather annoying to use Zhongli's pillar and spend the fight struggling to make sure your active character doesn't start climbing the pillar you created. If one could toggle off auto-climb and instead need to hold a key to climb, that would prevent this issue.

If auto-aim could be toggled off, this would allow one to better aim their attacks using a combination of the keyboard and the camera to direct they direction they want to attack.

Ideally, auto-aim would work like Clorinde's skill, wherein you do charge in the direction aimed with her skill, but auto-aim if you are not holding a direction... but for some reason, for everyone other than Clorinde one needs to hold a direction to make auto-aim work properly, which prevents one from attacking in the direction they are facing or holding.

Secondly, I'd make existing NPCs more relevant during quests. Rather than creating a new NPC for a quests story line, I'd try to have an existing NPCs play a role. This is one of the reasons why Mondstadt remains so beloved as almost all of its citizens have been fleshed out by taking a part in quest. Likewise, event NPCs like Turenna are more memorable because they have been reused,

Admittedly, Fontaine has done a nice job of this, and a good deal of NPCs there have intertwined stories.

Likewise, I'd probably have playable characters exist in the world...

...though, this would take away from their event appearances. E.g., if you could regularly visit Yoimiya, one would think even less of seeing her in the wild, thus things like the Childe + Yoimiya event would be even more likely to have been missed than it already was.

---------------

Third, I'd totally go for a cash grab by making a lot more character outfits. Especially for seasonal events. (That, and we'd probably get things like above mentioned Inazuma outfit for the Traveler for free.)

---------------

Fourth, I'd make it so one could still do the story for events that are relevant to the story.

---------------

Fifth, I'd fix more extreme character issues. E.g., Hydro Traveler. Likewise for Electro-Traveler's skill.

I'd adjust Sigewinne to not be so overbalanced. E.g., her ability to buff skill damage can't be used until she has over 30,000 HP, which means a key feature of her kit can't even be used until she is around level 70...

Add a pity system for artifacts similar to the gacha pity system.

So you could finally get the artifact you want on the set you want, with the stats you want and all that. that would be a massive lifesaver

Tighnari is the main character-

Imma be real diabolical here

• Nerf/Buff/rework every single character to 1.0 power standard for 4* and 5* respectively

• Add ICD to xiangling

• Remove neuv spin to win

• Fix ningguang charge attack assnimation

• Fontaine water everywhere

• Infinite sprinting stamina out of combat

• 100% dream solvent drop

• Aranara garland

• Equal distribution on artifact stat rates

• Old events

• Aloy constellation

Come to think of it, they've added ICD to barbara, the other free character, after 3.0 as well. Didn't hoyo nerf barbara three times, and way after her release as "bug fixes"? (burst range nerf that happened just this update, ICD in 3.0 or 3.1, and something related to riftwolves?)

So, maybe this does mean that they can nerf free characters. Or there just weren't a lot of barbara mains to care unlike what happened to neuvillette...but xiangling? Imagine if they actually give her ICD. It would be so interesting

Speaking of artifacts, I'd probably remove things like +ATK as that stat is so extremely useless... or at least buff said values.

E.g., 200 base attack + 454 weapon attack = 654 attack. A tiny 5% attack buff provides 32.7 attack... which means something like +14 attack is providing less than 2.2% attack.

A level 90 Diluc with a Song of Broken Pines is on the more extreme end, providing

334 base attack & 741 weapon attack for a total of 1075 base attack. 5% attack now provides 53.75 attack... which means +14 attack provides just a hair more than 1.3% attack.

Its not my idea i saw it on a youtube channel i think i forgor but I would make every voice less long world quest whit lore voiced and to avoid issue whit the size of game for people having issue whit their storage it would be optionnal you dont have to download it if you dont want. maybe that way a bit more people would pay more attention to those quest instead of just skipping throught them or just not doing them at all

If I were to become a genshin dev, I would optimize the rewards because the way they treated us on the anniversary is criminal. Also would bring in the 7day login rewards system in every patch similar to HSR. And give a huge redesign to them Natlan characters because the amount of melanin and culturally accurate appearance they lack is criminal.

1st, I am a massive fire emblem fan, played multiple games in the series for years, so I would for example implement two features that are common in every fire emblem game. The first being one feature also adore in other games like persona5royal.

Event theater. I would put a event theater so that when you complete a quest you can replay the dialog and scene, you could replay cutscenes, see the birthday art often produced for characters on twitter /hoyolab by mihoyo. Rewatch imagery like the shenhe song and yunjin cutscene, event cut scenes, archon quest cutscenes. Etc. I just feel like that way you can relive the game without restarting. fire emblem three houses does this perfectly imo.

You Can also play songs in the event galley(maybe they could add the musical device in the teapot for example. and actually add every single track Ingame.)

2nd, I would add another layer to the friendship system, because right now it feels unfinished to me

Dgmw. Name cards are great , but it just feels strange that you ONLY get voice lines and a namecard. Nothing else. No special FL10 voiceline.

Which is why I would add a special item and cut scene for every ingame character. The item would change depending on the character, (Some characters that show a platonic view of the traveler or familial would receive the item and a cut scene where their treating the traveler like family or a sibling.)

If you were to use the item on childe for example, it would a cutscene of him swearing you as his all-time rival, and to one-day beat you, or whatever would fit. Some characters that might or might not show a attraction to traveler would receive a cutscene and different reaction to the item.

Im not saying I ship anyone with the traveler. Or have anyone in mind, Because that could be a feature voted on by the fans. But I just feel like if your running a marathon, why stop before the goal?

Obviously not every character has romantic feelings with the traveler. Heck, most probably dont. But. It would still be nice to see a friendship lvl10 voiceline and a cut scene with a character once your reach that point of a bond. Maybe for example ittos cutscenes is where he invites you to join the gang after you give the item, and special art(saved in the galley mentioned before)

This stretches to literally every character. You can expand more on the friendship system without making it romantic or cringe.

But on the otherhand, you can also add romantic choices for characters without forcing it to every character and making it mandatory that the character feels that way. Fire emblem engage actually shows that approach.

you can max out bond with a character and get a special interaction. But not everyone is platonic, and not everyone is romantic. It actually depends on the character and their outlook. Their interactions.

It would also give more relevance and lines to certain characters. Surely theirs a few people that main mika, amber, aloy, razor, kaveh or dehya .that would not mind seeing more interaction or lines from their main.

For example, wanderer is a popular character. Theirs plenty of wanderer simps. Im sure at least 100thousand of them wouldn't mind at all if their was a romantic option for wanderer, and if thats out of character, or maybe a special platonic cutscene where he finds you a person he trusts as a friend, like his friend from tatarasuna.

It just feels like, what's the point of a friendship system if you dont go for that angle where they see you as a dear friend?

Namecards? Backstory?

The backstory can be just unlocked with lvls, like honkai star rail. (Sorry if its a bit of a rant. Just really bugged by that. its like attempting to make a 3 layer chocolate cake, and stopping at two)

Another thing (3rd) I would add is reruns of past events unlocked with keys you get from doing commissions.

I also (4th) would add a in-game help board in mondstadt. Picture this, you Cant solve a puzzle, dont have a phone or computer(or maybe you just cant find the answer on google), and don't have hoyolab. You can't really look up answers to puzzles or guides in that situation, or at least, reasonable to the situation ones. So I would add a in-game help board. Where you take a screenshot or video of your problem, put text explaining your question or problem, and put it on a global help board in-game, where if people see your problem they can look at the clip and help.

And if no one responds, a team at mihoyo specially made for this mechanic that have completed the game and have all the answers to puzzles thus far will then look at the problem and help you (as in, if no one responds for 31 days. )

This would help plenty of newbie players who are stuck during quests or areas. I myself have experienced this with Enkanomiya where when it first released, I could barely understand how to do the puzzles and was confused, same with inazuma. The help with puzzles wouldn't Stop situations like, and while I'm totally for more difficult puzzles, their should be something to help those struggling.

So I would add 4 things. Two/four from typical fire emblem games. 3/4 being QoL.

Dialogue skip button, chests reset every x.0 update, buff Dehya, Venti's second story quest, revise Mondstadt and Liyue archon quests to have a higher-budget and newer feel, make Paimon less annoying
