Apparently the collectibles that we gather, are something that the collectors actually want and "need". So why then do we hand them things that they want and need, and in return, have to stick our hand in a grab bag, and pull out some misc. thing in return?
When I make a trade with someone, it is usually because I am giving them something they want, and getting something that I want in exchange.
I would like to see something like the reward selection that is offered when you complete a quest when I offer a trade with the collectors.
