Was just looking a bit through the changes they did with Ungrim when I opened the tech tree.
I cannot help but feeling that this tech tree is bloated by now. There are easily a few techs that could get cut because they are redundant on the economy side of things.
Military side of things could do with a regrouping. Several smaller groups instead one big chunk you know.
I really hope the Dwarfs get a rework of their tech tree.
