Well, look at it this way: both Jills are valid. Since MC(not us as narrative deciders) picks what he wants. Chick MC will fully enjoy vanilla Jill. While a more Neutral to DIKish MC will enjoy Darth Jill more. So I think DPC actually created a divide that will satisfy 2 types. The Jill Purists(naive, vanilla, basic bitch, chick) and stronger willed and determined Jill, a Jill that fights for what she wants. A side of which we first saw when she destroys Tybalt. This was actually a great move on DPC's part.
Because who ever plays Jill and really enjoys Jill route, the banana costume is so on point her socially retarded antics. It's so Jill. And I for one loved that run, I laughed and enjoyed it.
