I love the "Sell Unsuable Equipment" option when leveling or doing quests.

But as I now often PM in raids, I noticed my warlock sold Leather, Mail and Plate items that I carry around after bosses for trading later, if I e.g. use a rep bot or rep in a city while refreshing buffs.

So far, I was able to get everything back, but that's always a good jump start of adrenaline :)

Can this option be amended by "Unusable Equipment unless it's BoP but still tradeable?"
