Actually, I think Cheesy has a point. If you're making a hard modpack, then Dartcraft doesn't exactly fit. You may not be able to use the diamonds you mined to make tools, but if you got Dartcraft tools, it doesn't matter. With it, you can practically dominate everything without diamonds. It defeats the very reason of having Iguana's build up for Tinkers construct, cuz no one will bother to use it.
