It's exactly what I've done, I know that the enemies never try to attack the outer gate if they have no battering ram so I intentionally left one siege tower intact so I could focus all my troops on one point to not be spread out thin. But they just abandon it on the field and leave even when it's at full health. It's just beyond me.
I think blunt weapons should have an increased probability of wounding enemies but should still have the chance to kill them. Something like a sword having a 10% chance of wounding instead of killing and a mace a 40% chance, and the threshold would only increase with your medicine skill.
That is good to hear, I finally decided to torture myself with that save file and see what would happen if I toughed wave after wave, they were finally defeated after enough lords from my kingdom gathered around the besieging army and engaged them in open field combat after their 4th failed attempt on the walls of the city.
My bad, what I meant was that if the situation is that bad that they had to retreat while attacking the walls then they should be wise enough to just abandon the siege altogether. Not try again for the millionth time without success.
That's why my suggestion is that the attacking army should have the option to abandon the siege altogether if they lost too many troops.
I don't know if I'd go as far as saying that they're trying to make the game intentionally less fun, to me it feels more like an attempt to make things more balanced or realistic by trying out new concepts which don't always work as intended. Like a process of trial and error, see which stuff works and which doesn't.
It's not that big of an inconvenience, but thank you!
