If the ladders would stop properly (like they did pre-patch), there would be no need for such weird constructions.
I don't really get how chadz plans things. On one hand he "wastes" time making some new wall models to replace the sinking castle walls, which to 99% is to improve the look of the game, but on the other hand he implements totally retarded ladders, which can only be placed if 30m behind you is literally NOTHING (stay away from trees, rocks and hills!), and IF you manage to make a ladder cross the 90°-angle-to the ground it will stop half way in the obstacle you actually wanted to climb up.
It is utter bullshit. Really. Change it!
