your units can also charge starting from less distance and maintain the charge for longer as well as elevation bonuses.

combat bonus in melee for height advantage means that peasants can even hold off RKs for quite a while.

missiles get crazy range bonuses. archers can outrange longbows

bouncing catapult shots are unreal and even units like naptha and jav can give huge range boost if you target nearby unit and it shoots overhead to hit units all the way at the foot of the mountain!

one lucky shot from a naptha once went all the way down a mountain and blew up half a dozen RKs including the opposition general!
