Yes, part of me wants an FAQ which addresses these trait oversights:
Elrond and Daughter of the Nimrodel should have the Healer trait
Dain Ironfoot should be Noble
Legolas should be an Archer
Ally Denethor should be a Steward
Rivendell Minstrel should be a Minstrel
Many others which I cannot recall right now
Except Noble, these traits have little effect on the game, so I can see why this would not be a high priority. Still, the theme is so right in so many ways, it makes it more noticeable when there are missing details.
