you dont get it, having there be limits of equal value will not change the fact, that consoles cannot handle a disconnect during a trade like a PC can, i.e. two players trade a Gjalla and Icebreaker because they each do not have one of the other, hit accept trade, hard quit the game, player who quit still has Gjalla/Icebreaker player who remained in game got the new Gjalla/Icebreaker they wanted, item duped, whole game rendered useless, i.e. Diablo 3 for consoles
