Trading evolution is dull and pointless these days because you can just arrange with some stranger over the internet to do you a favor and make the trade. It's not like it used to be with you having to find friends IN REAL LIFE and make trades.
Totally boring and just makes you waste your time doing something that doesn't add anything to the overall fun factor of the game.
