Why would anyone Trade anything if your desperate for crafting materials?
Why wouldn't I? Over the course of a week I play with the same 8-10 people. If I don't need said item or gear for my builds I would gladly help out a friend. If they are stronger, I am stronger making our future times playing together better. I've had people willing to kill themselves in the DZ to pass a HE they didn't want to other people.
