So I just hit 100 with my smithing skill tonight, crafted a whole set of Dragon Heavy Armor, upgraded it to legendary quality, and realized that it offers less armor rating than the Daedric set. Why isn't Daedric Armor unlocked at 100 instead? The Daedric set was more annoying to craft also. After looking, the only argument I can find for why Dragon armor has a lower rating is because it is lighter than Daedric. This point is invalid seeing as how the Heavy Armor tree allows you to make all heavy armor weightless.
What a waste.
