Okay so... this exchange thing, when you do open it for the higher end stuff... Is there going to be calculations set in that if I try to exchange a very rare item, I'm guaranteed an item of equal rarity or do I risk getting a craptastic item?

I seriously don't want to get rid of my old extras that I can't seem to sell if I'm running the risk of getting an item that is 100 times lesser in value.
