Whether it be a variation of another character's kit, an improvement over it, their element, or a completely different playstyle, all of these aspects of a character's kit must be carefully considered when releasing new characters in a Gacha game. Not to mention, Gacha games usually have an absurd number of playable characters which might make the game slightly intimidating for new players to really get into. Honkai: Star Rail is no different from other Gacha games on this topic, amassing 57 playable characters as of version 2.4.
