How would increasing the number of items allowed in the trade window lower the possibility of being scamed? To me it would increase the number of scams. The more items the harder it is to see which items got changed. 4 items is enough imo. But again i dont believe in scammers just impatient people. People that dont take a few seconds to see what they are acutely buying, and if it is the item/gold that they agreed to.
