Genshin Impact and Honkai: Star Rail are both games made by the same developer, HoYoverse. While Genshin Impact has been out for roughly three years, Honkai: Star Rail has only been out for roughly eight months. Although they have a lot of things in common, like both being gacha games, there are some player quality of life improvements that are present in Star Rail that Genshin lacks. These improvements range in use from new players to those at a high Trailblazer level. If brought to Genshin in some way, shape or form, it would be a boon to all players, regardless of where they're at in the story.
