I know it sounds strange and maybe out of line but i think that if the leggendaries encounters or the method they are obtained through could be repeated multiple times changing their shininess, iv's, nature ecc... Of course the leggendary pokemon will be replaced by the new one in order to not create a mass chaos of leggendaries in the server. Just so that people who want can hunt their leggendaries in their shiny forms, could this be possible?
