Notes:

This is the one thing I see ALL the time on the GTS. Impossible demands for legendaries, especially Mew. GTS would be so much better if we could do the opposite of what it provides us- select a Pokemon from our own collection and then run a search for who wants that particular Pokemon (level, gender, & whatnot), instead of having to put it into the GTS and hope for the best or just look up the Pokemon we want and be at the mercy of the other party.

EDIT: I know there's a lot more stuff wrong with GTS than shown in this picture, but I wanted to capture the gist of what irks me the most.

But when it DOES delivier, by George, does it deliver.
