When appraising an item it gives you a rough idea of what sort of value it has. Now I know it's sooo much fun to guess, and ask around, and just plain not know anything about numbers or how anything works in game, but I'm thinking apprasal could be expanded to include a vague idea of how much damage, how much armor, how well you could use something, what state of disrepair, etc etc. My main idea was so it would be easier to tell. Are those welders pants more protective than du-wear cargos? It would be reasonable to assume that you could estimate that via a close examination, especially if you know more about combat, or clothing manufacture.
