This is unironically the TRVKE.
When every character has big boobs, nobody has big boobs. Big boobs characters' boobs are big because the others don't have big boobs. There's this contrast that makes specific characters stand out.
Hence diversity is unironically important in a gacha. Not the woke diversity, but diverse attractive characters of all kind including males. So in one game you can have attractive hag, attractive hebe, attractive loli, attractive bara furry, attractive male, attractive boy, without them overshadowing or clashing with each other and attracting the largest audience possible.
