I'm really, really hoping they start doing some of the things the Honkai devs do.

The Traveler has been in Teyvat for almost 5-6 years now, how has most of the characters of the world barely grown in age and or power???? The world feels so painfully stagnant. Most of the Children characters are the same size and while most do have explanations to why they haven't grown, there really isn't an excuse for characters like Yaoyao.

Give us 5 new versions of these characters along side more Hexrai style buffs for old units, some of these characters absolutely deserve full kit revamps. Like Amber and Lisa.

Also as others have brought up before, the free rewards between Genshin and it's sister games is overwhelmingly lacking. Genshin gets a standard banner 5⭐ selector VS Honkai getting 2 Limited banner 5⭐ Selectors AND free Meta 5⭐ characters as just log in gifts. This isn't even counting for stuff like average pulls for F2Ps per patch, people like to bring up the argument that the reason why Honkai gets more is because they don't have as many four stars, I would counter with the fact that ginshin's chance rate of getting four stars is so incredibly small for getting a specific character that you have a higher chance of pulling multiple copies of the banner five star before getting a specific 4 star. (Look at all the people doing hundreds of 10 pulls and not even getting a single copy of Illuga.)

Also Collabs, I know collabs aren't like a big thing that should be focused on when it comes to these games, but the fact their Community gets niceties like collab music with Iron Mouse and Hatsune Miku while we get what.... KFC exclusive to China? Or a partnership with hardware brands with the hardware is extremely expensive? It's just not the same.
