Nah, he probably meant PC nightborne models, fem models in particular, they're quite different from NPC models. It's not about animations.
For instance, NPC female models have thicker more muscular thighs, different shoulder to waist ratio, different faces, more skin colour options, and so on. So there's ways to improve PC fem models by adding more face options w/ squinty eyes, 2 skin colour options that aren't available to PC nightborne, etc. Obv, it's too late to fix their thigh/leg circumference... or nah? o_O
And PC male models are just a mess
