Trading was removed from D3. The game is boring as a result. Botting rampant. D4 suggestion

Trading doesn’t have to lead to illegal websites.
Trading doesn’t have to be time consuming.
Trading doesn’t have to be restricted.

I have come up with an anonymous trade matchmaking system that stops illegal websites from being able to operate but still allows people to trade items.

It’s not an auction house. It’s unfortunately not “open” trade, meaning you can’t walk up to someone and request trade. All trades are handled through the matchmaking system. But it is unrestricted, you can trade anything. No limitations.

It’s a search that performs in the background while you continue to play, until it finds someone who is selling that item.

When the system finds a match, your names are hidden so that you’re both anonymous. You communicate with pre-defined chat bubbles (like Hearthstone) and the ability to highlight items to show interest.

This system streamlines the process, making it possible to continue playing while you search, it stops illegal websites from operating, and it allows you to trade anything for anything, no restrictions.

Yes, it takes away the “social” aspect, since you cannot chat and you have no idea who you are trading with, but it is a compromise if people really are serious about wanting meaningful trade and economy in Diablo 4.
