Just a thought on shinies as prizes. Many shiny traders have expressed concern when I have spoken to them about the number of rare shinies given as official tournament prizes. Tournaments should have good prizes, no doubt, but the number of official tournaments and the number of rare shiny prizes given in each is enough to threaten the shiny market.
This isn't a problem that should be taken lightly, because shiny trading, no matter how it is regarded by other players, is one of the main post-story line activities, and shouldn't be considered inferior to competitive play. I am sure many shiny traders wouldn't object to shiny prizes, but maybe they should be less valuable.
