I think Aura accounts for the strength of the humans in Vytal. You could account for the complexity of the weapon design by saying that Ruby and the rest of the gang are not exactly normal children. Do all children in Vytal go through the weapons training that Ruby, Weiss, Yang, Pyrrha....etc all went through? Or just "special" children that probably displayed an aptitude for this sort of stuff early on?
