I am not sure if anyone has suggest this but I would like to suggest to add only normal legendary to maps, because its really boring to just look for shiny pokemon on map, if we add legys to the map it will encourge people to start map hunts and the use of masterball

the catch rate of the legendary:
pokeball: 1%
greatball: 5%
ultraball: 15%
masterball: 100%

encounter rate:
.5%-2% depending on the legy

right now i see no use of masterball, if theres legys there will be a use of it
plz comment on it :D

But some can be bought in the games corner.
But it's actually a good idea.
