And it should be like that. One highly trained knight can solo dozon of low skill oponents and even more peasants. Watch on youtube "Knight of hope" and bear in might that this is not fiction, its very realistic scenario there.
As for looters ... comone... one thing is throwing rocks on static targets and something different is aiming full speed horse thats circling around not in single pathern while shoting back, my friends around dying, arrow on my leg etc ...
Do you know why Polish Husaria could win even outnubered 1:10? Ok, they were highly skilled, very good equiped but there was also psychology there. Enemies literatly was ****ting their pants seeing charge. They knew they have 1 shot and if it miss they are dead. Their hand are starting to shake and they were getting even more nervous and hand are shaking even more. Thats why most of missile units are that bad against cavalery. And here we have some lowest of the low with stones that have like 50-70% accuracy on fast moving target, with stones that can penetrate decent armour and you are saying its as it should be? Bullsh....
