That's exactly why I hated trading all throughout the first 3 generations. The external device requirement was pretty stupid, and not having anyone to trade with made it impossible. :P
Well I guess I'll make a new topic since activity is pretty ghastly in here. ._.
We've seen all sorts of evolution methods, even pertaining to trading (i.e. w/items and trading two pokemon at once). With the coming generations (assuming there are), what sort of innovations would you predict/want out of trade evolutions?
