Ladders are still reasonably viable. They can't collapse like towers with your unit inside. I've done that to the AI before. It reached the walls and the enemy troops started climbing only for the tower to burn down and collapse with a unit trapped inside. Only 1 man made it to the walls and was promptly cut down.![]()
Sapping is indeed extremely effective and low risk in RTW. Adding counter mining etc. wouldn't be a bad idea. Maybe give the defenders some build points for counter mining tunnels, stakes behind gate, that kinda thing.
