You would think there would be a good list of 10 things you could think of to say to someone wearing a full set of Daedric. Like this,
In my best Arnold voice: "What's that? Daedric Armor? What are you doing, communing with the Daedra? Get out of here".
Or random old lady as you pass: "Ahh! Begone, Daedra worshipper!!"
Or a small child: "My mommy tells me only people who worship Daedra where Daedric armor..."
Or another Arnold: "Where'd you get that Daedric armor? Working for the Daedra?"
Something, anything would have worked. Daedric after all is quite rare (as it should be). I was just disappointed that no one commented on it. Was it just my game, or is there really no comments in the game for Daedric armor? Oh well. I hope they address this for the next TES game.
And by the way, yes I know this is a very minor nitpick. I absolutely love Skyrim and think it's great. But this is one small case where I expected a bit more.
I think it's because they're afraid. They're afraid that if they say the wrong thing or look at you the wrong way, your Billy bad(expletive) self will cut them in pieces and ship the parts to each of their family members.
But if you want a more practical reason, it was probably an oversight by the development team and missed implementation.
