@Memor-X I have discussed this in mine room quite a bit, so if you want you could look here. Just drop me a ping if you want write access, I have switched the room in gallery for some reason some time ago.
usually a gacha tries to force players into getting new characters / items by crafting new events in a way that makes the player experience miserable if they don't own the new character.
This can be made in many way: extreme powercreep (old characters "age out" fast and are too weak to handle the new content"), "boosted characters" systems (basically the same, new character are given some bonuses like more atk or faster skill CD so the old one are artificially disadvantaged), debuff lock-in (the boss uses a set of debuff that only the new character handles efficiently) and so on.
This work very well in turn based "card" gacha where there are thousands of characters and debuff.
Genshin has an action "Sword of Mana style" battle system, open 3d world and so on so those gymmiks don't really work (you could try powercreep but it would become very evident and damage the open world exploration too)
For that reason Genshin has to sell character via "Fanservice".
It has to make the character look "cool" or "adorable" when it is on sale.
Example: Yoimiya is on sale. At the same time release Yoimiya centered quest that ends with pure fanservice "ImaAdorable" scene.
Forget about her for the next month while she is not buyable, then as soon as she reruns drop part two, 20% more adorable.
This has a problem though: character are focused on only when on sale and "left out" when they are not because the game needs to fanservice someone else.
Therefore you only have the main character being universally present while everyone else is just a "background pony" that is at the center of the show only during their episode.
It requires a deliberate style of narration.
@Memor-X so, after this premise (that wasn't short as I wanted, forgive me please) my point simply is that the trailer for this new game almost look like a Persona game. The five character don't look just "background fillers" to a main one, it looks like the plot is centered around all five of them. And that would not work for a gacha.
First, you would need to give all 5 to the player because anything else would cause an huge dissonance. Second, you now have 5 character already taking up the story time and there is no space left for promoting the other gacha ones.
For comparison, the first story arc of Genshin gives out for free some of the core Knight of Favonius characters (Kaeya, Amber and Lisa) but they aren't the core of the story outside their specific subplots.
