I think the game is honestly still in beta. They couldn't hold back on releasing it because if they did, all the kids playing would be back in school, s they released a largely buggy, incomplete game. Not that it isn't awesome, that's just how things are. I think trading will be implemented in the future, I'm also honestly hoping for a friend list type thing as well. So you can trade with your friends and things. I'll be disappointed if a wondertrade type system was introduced (plus it would overload the servers) but one on one trading would warm my heart.
