I'm really talking about two issues here but-
I'm not sure about this, but it seems to me that blighted items were introduced to be a replacement for cool (stat and appearance) weapon drops that other games have. This is all fine and well... accept they usually are nearly useless unless you are incredibly lucky, and they look downright ugly on your charactor.
I rarely find a blighted item I want to actually equip, and when I do, it looks like my charactor is wearing a clothing pice that has been floating around in the Boston city sewer system for a while. (probably smells like it too)
May I ask that blighted items be made dyeble using dye kits? It's bad enough that they never have any unique appearances or anything, but they aren't even appealing to the eye to wear, it's like whoever thought them up wanted to do the best they could to discourage blighted item use, even if someone did find somthing with half way cool stats.
