The one thing I think that could save trade in this game is simply making Legendary Aspects tradable. This brings some amount of value to all legendaries you find.
Finding perfect rolled Aspects and perfect rolled Rare bases would make the trade economy very intriguing. We can trade for 1 half of a good item but not the other currently.
Having to break down the item in order to trade the aspect i believe would also cut down on the sellability of the aspects especially through botting.
i hope not. rares being tradeable is already too much and will create shady 3rd party RMTs.
I hear you. Thats why i think there is a need to either shut down trade or open it more up. Im concerned this meeting in the middle will only bring the worst of both worlds instead of the best.
I do think the process of having to break down the legendar item the Aspect is on will alreadybhelp against bots somewhat. But yes. Bots and 3rd party sites and ebay will always be a thing in games where trade is involved.
My solution for opening up trade completely would be to have an open in game market place with an in game farmable currency. Then have the currency only be exchangable through the market place and do not allow private trades so that it cannot be sold. Diablo Immortal has something like this with its market place but its to centered around its pay to win items. If done right for d4 it could be a verybpopular trading system.
