If this was already mentioned than please lock this.
It never happened to me, but I'm pretty sure lots of people had troubles trading items from the marketplace because lots of them have the same name.
Today I wanted to check some offers for a churburg armour, the problem is that there are three kind of churburg armours and each with different price/appearance. And what I was looking for was a (non heirloomed) churburg armour with mail.
I won't try to trade with another player in the market for a mailed churburg because it might happen that I will be given a cloth churburg (red or blue).
I hope thiswill be fixed in the next patch
