Blades Armor is a good example of game mechanics taking over sense. But it's understandable. With the way it's built, with an articulated torso, sectioned shoulders, and use of brigandine rather than chain, it'd be more of a "medium weight" armor, though even that's a gross oversimplification. It's still an extremely flexible set of light plate though.

It's easily my favorite armor in the game. It's both slim and simple, but just seems to radiate power. It looks absolutely awesome without deliberately trying to do so (I'm looking at you, Nordic Carved).

Dragonbane and Dawnbreaker. Now, now Elisif truly looks the part of the Dragonborn. Bonus: Njada Stonebrain's information is now wildly off, save for the "unholy" (lol!) sword.

And for the record, I agree with Delphine, but only to a certain point. Killing the one she demands just doesn't make sense. Maybe Brynjolf will be able to point that out to her.
