This is not an abnormality but realty (historical, obligatory fashion) for those Chinese nobles, etc.
What you are posting is actually an idealized scheme for the first semester medical students: visit a local beach or anatomical theater if you really need realistic prototypes. I have enough realism in RL and do not want to see it in a game.
This is a taste matter: do not like what a mod author is proposing ? model yourself a realistic, anatomically correct and hot variant. I am sure that all of us would be happy to see it, play MW with it.
I have made dozens of BB male and female body shape modifications, with extra bones and without as well as not BB based bodies for NPCs. I can post pictures. I am not an artist but do know technical aspects of 3D body modeling.
You know what, I think I have an explanation of our taste differences, body shape preferences: Americans statistically (scientific fact) are more variable in body shape, face morphs, and other anthropometrical parameters than we, Germans. Probably, therefore you prefer more "standardized" ideal shapes, and I am missing it in RL seeking exaggerated variety in a game.
Nicholiathan, I am very sorry for this off-topic mess. I am shutting up.
