Just my little say,... Although no model is perfect, I do think some of these errors in the bosy mesh result in incorrect posing, like using one joint to move the arm, or leg, when you get a much better result when using a comination. I where possible try to think how i move, then as far as the model will allow replicate it... I see all the weird shoulders on M3 & sometimes V3, and i know its because of the way its been over posed... ;)
