No one has seen dragons for many many years, and whatever gear left with dragon scale/bone parts in it must've been made a long time ago... but yet here comes a gal/guy that just escape execution and within weeks/months can craft a legendary quality dragonbone sets... what? O.o....
Well that's because dragons have just come back thanks to Alduin the son of Akatosh. So yeah, theres a lot more dragon bones and scales floating around, so i could see how it would be easy to acquire.
I'd also like to add
Does anyone else feel like there should be some other better type of armor forged from dragon parts? i mean c'mon, you kill like 4-5 dragons and u have a set of dragon armor, which isnt even the best armor for heavy armor users.
Just feels like there should be a harder armor to craft, one requiring more materials, and rarer ones from harder dragons.
