Il n'y aura aucun système d'échange face à face comme se fut le cas pour Guild Wars. Nous aurons les mails à la plac :

Hey guys,
The no face-to-face trade is a real decision and it’s primarily a question of trust (as many of you have noted). But it’s also a decision to protect players from scamming and protect the economy from black-markets. Let’s run through some quick examples.
1) Give something to my friend. – As several of you noted, target your friend, right click the item and select ‘mail-to…’. Done, this works in contact list, guild list, or in world anywhere without having to ‘meet’ them or ‘catch’ them.
2) Get a fair price for an item (anti-scam). – Because ALL trading goes through the trading post we can guarantee that highest bidder meets lowest seller and we can give every player the benefit of current market information.
3) Barter item-for-item. This is the grey area and also the most risky kind of trade because even with UI many items look alike in icon and many social engineering scams take place in this kind of system. It’s a risky trade environment which is why when you support it you have to have these multi-stage UI’s where everyone double-checks everything, and then eventually get’s lazy and stops double-checking and gets scammed anyways.
In the end we decided with super easy access to mail for trusted trades and trading post for untrusted trades that such a system wasn’t worth the risk, complication, and fragmenting the player market off of the trading post..
In testing we’ve found that mail is easier 90% of the time we’d want trade and the other 10% trading post is far safer and avoids drama and thing like random trade windows being thrown at you and lots of other unsavory hawking in game.
Hope that all makes sense.
