So I’m past the goblin king and am just dorking around building stuff waiting for expansions. Nothing more than my opinion, but wood iron is the friggin worst. So much effort mining for a very strong, very short pole.
So my suggestion is to replace wood iron beams with iron brackets/bracers. It could still cost the same amount of iron but you would instead just attach it to the joints or intersections of existing hard wood/regular beams strengthening the load bearing potential. This would smooth out the building experience, allow you to more functionally build on existing structures, and get more bang for your buck in height and width. Think it would look better visually too.
Not expecting this to be popular as there are mechanics of the game I’m likely ignorant of. But please don’t eat me alive. Just a random idea to improve the gaming experience.
