Asking tacticsoft for trading items wasn't added but changing items is a similar thing.
But changing items will be a good thing since ill show you:

-To change an item you must use Tokens
-Changing items will be the same item as category as like Torso, Top weaons, swords etc...

This simply won't be implemented into the game. There have been many suggestions for trading, but think about it. If this is the case, only people with tokens can get it. Also, those who hack tokens can also get the advantage of doing this for free. And finally, as said in the Q&A video, it will cost quite a bit of money to start it up.
