Decimation acting like uniform faces is always on

It used to be more like this, flat areas would be highly decimated. It seems like it distributes decimation evenly now. It used to give me perfect, amazing results but IDK if my use-cases have changed it or it’s just changed, but now i once again have to go in there manually and decimate flat surfaces (which is hard because it can seep onto the other side of an object if you don’t get your cursor radius small enough)
