At least they got the casualties more or less accurate this time. Defenders of a city wall or stronghold should be able to hold off between 5 and 10 times their number if properly prepared. Also losing 4000 defenders versus 25000 dead attackers is more realistic than previous seige examples in this story.
ah Li Mu ...or Riboku in Kingdom..the nemesis of Qin...would be interesting match up against BaiQI...funny though it seems he forgot that the country of dragons was the one who one the warring states in the end..!
