if you look up you will find my post talking about this multiple times. to me, clonning is not just a solution to a problem the game has, but also a way to make the game more interesting. being able to clone other girls to put them in the bordello would add so much more interesting ways to enjoy the game, not only because when you unlock their MC, you lose them to earn money or their scenes in the bordello.
i still dont get why they havent implemented that. as a side note, i also think they should add a way to contract the villains permanently. maybe add a quest or just pay alot of money. maybe have a salary.
overall there are so many interesting things they could add that arent hard to implement but that would make the game far more fun to play.
as a side note, adding clones would also give an option to keep your girls, and the bordello hoes separate for those who dont want to share their toys. since lex is a perfectionist, i would think he wouldnt enjoy playing with used toys...
