I am a level 7, and have found all of what you said, and have found Orc and Ancient Nord items all in my travels... You must have not explored too many caves, or dungeons... We still got a long way to go, dont you worry.
No, I've found Orc and Ancient Nord stuff. It's plentiful. As is Iron and Hide. But that's it.
I haven't seen a
single piece of elven, glass, ebony, steel, and whatever else armor/weaponry there is. And I've done plenty of dungeons for the 12 or so hours I've thrown into the game so far.
