You`re not wrong Dragonbone weapons and armour will be included in the Dawnguard DLC.They will be even more powerful than Daedric too Did you notice the new type of arrow in the trailer?? It had 3 spikes on the arrowhead - looks interesting,I`ll definately join the Dawnguard first to explore the new crafting skills.
I'm using the Steam Workshop's dragonbone weapons mod, and it has some excelent concepts. The weapons are placed just between ebony and daedric, which should be their rightfull place, and the design is wonderfully crude and barbaric, perfect for a pure warrior character, like an orc or a redguard. I hope the weapons introduced by the DLC won't be too different from the mod's weapons , because I've got used to them.
