I think that their should be a trade system for example when you trade the trade wont be accepted till they trade you back that way you wont need the 5 days rule. It would be like a box that pops up and then what ever you're gifting is in one box and the thing the trader is gifting is in another box and theirs a button that say accept trade. I cant make a visual look right now but I might work more on this idea later.
