why do we have to automate everything in order to enjoy using this program?

Fine tuning will always remain, but because the hip is in the very root differences there result in gross differences all over. Compensating for those differences via a script gives you at least a decent starting point to play, adjusting arm and hand positions etc.

This being said, LaFemmee takes Victoria3 poses very well. I did dig up some old pose sets by Schlabber and found they needed very few adjustments.
