They didn't push hard enough into ambiguity. Have Rachel be friendly/charming towards Chloe, but maintain some degree of emotional distance. Have her rope Chloe into her schemes in ways which could be interpreted as both "friendly" and "using". Chloe is supposed to become obsessed, but Rachel's position is supposed to be unclear (at best).
Having the game essentially spell it all out, while also fucking with other parts of Rachel's character, just shits on what made her interesting in the original game.

The original game makes it pretty clear that she is bi, she makes various comments about guys, keeps condoms in her wallet, etc. You could probably argue that she leans more towards women though, especially as romantic partners.
