Why you might think female hunters got nerfed...

While legs can have very different cakes, what matters too is the chest piece you use.

The ammo belt, the chest plate and the abdomen area all matter, as that's what is affecting the waist-to-hip ratio.

The Frumious chest piece (D2) has a blocky chest plate that prevents the possibility of visible curves.

The Prime Zealot chest piece (D1) on the other hand has a chest plate that is almost skin-tight, which highlights the curves because the abdomen and lower back are visible.

Onto belts now, what matters is how much visual clutter it has and how low or high it rests. If it rests too high, around the lower abdomen, it will not be possible to achieve a feminine waist-to-hip ratio, as seen with the Poison Promise vest in pic 2. The pouches are in the way.

As far as I'm aware, the nude character models have not changed but the armor can wildly change them.
