Looking at the maps in the Workshop you see that there are many cliffs, mountains, rivers just to limit the use of Walls. Why? Because we are blessed with paper Walls.

On a lot of maps you can't build a Castle, there is just a small part to place a Wall.
That's not what this game is intended for.

In the Mod Walls. Towers, Gates, Hoardings, Engine Towers have 2-3 times hitpoints so now we can build a real Castle and defend it. Especially because there are extra countermeasures for the Siege Camps, appearing out of nothing.

Another thing, with Mantraps, Pitch, Dogcages, Watchtowers placeable outside your territory there are new tactical options. For instance, it is fun to disturb the enemy supply lines with these nasty Dogs. Crying Miners, dying Oxes, and the happy growling of your best friends make your day.

Maybe it is possible to make maps that 'use' these new elements. Just thinking...
Would be nice if a creative mind can do something.

I'm a lousy designer so this is for the real artists :)
