it's not so easy to make a realistic game, bannerlord it's taking a step forward, maybe in 20 years we will have a VR game where you can punch hens and lick the stone wall...
it's as great as it can be right now...
you people want everything with no idea how hard is to make it, a simple "go to sleep" AI function takes hours to create and debug... then when you add variables like thirst and piss and whatever the work gets longer...
of course it's just one ladder, there are 150 max NPC on the map, what will you do with 100 ladders? slow down loading time and decrease fun in gameplay... they did their best at that time and now they made it so there is a ram, ladder, and a siege tower in the same battle, HAPPY?
