I think there should be a way to find rare pokes on maps but it automatically change the layout of the poke ones someone has found it that way they don't always get it and pass the info on

I do think there should be more options to gain rainbow/shadow pokes, but not on the maps, because the maps are just for the beginners, after that it sall about leveling/training. Anyways to change the picture of the pokemon when its a shiny, would be a good idea, since sometimes i click too fast because i think its just a regular poke.
