Again, would be nice to get a developer comment on the designs.
If they came out and said that only the elven weapon designs and fancy armor designs are in the game currently, we wouldn't have to worry or discuss these at length.
They should at least provide a generic or utilitarian version of armor designs, because not all adventurers are pompous fools paladins of Sune or Lathander who want overly fancy decorated golden armor and weapons. Stealthy, woodsy and sinister characters wear armor, too.
