Reason for joining: I love trade evolutions, my favorite Pokemon even evolves with one.
Answer to the current topic:
I don't think much can be done to change it, I mean, as of now all you can do is trade, or trade with item. Maybe trade with max happiness or something but I don't think there is much innovation coming. I do love how evolution by trade + item makes new evlutions in future gens possible though.
