In 95% of cases, you can bypass one guard and pass through, which is not possible with the entrance to the dungeon. The moral of this story is that regular passages are regular passages, going down to the dungeon is going down to the dungeon, two-way passages are two-way passages, and one-way passages are one-way passages, and IMHO, it's not worth equating one with the other.
I just wanted to convey that one-way passages were clearly designed for companies and fixed maps because the connections on the templates do not imply "only entrance".
"Сущность войны — обман. Искусный должен изображать неумелость. При готовности атаковать демонстрируй подчинение. Когда ты близок — кажись далёким, но когда ты очень далеко — притворись, будто ты рядом."
