I would love to see a private trade system implemented. This could be used for many things, but I mostly want it to help my guildmates with gear and resources as well as create a better feeling of community.

Idk man. They didn't have that in the pc version either.

The market system that is currently in place is ideally the only trade system thats going to be implimented

With you being able to trade gear from one account to another, its very easy for phishers to take your stuff, and be on their way.
with the market system they have to have the gold in order to be able to take anything.

Market system in place is more than likely the only system that will be in the game.
