Honestly, of all the features Pokemon has I feel Shinies are one of the most pointless and should probably be scrapped in favour of something more interesting.
>Oh boy, it's identical to the other Pokemon I caught but the colours are slightly different! And it took hours of farming to catch!
Unironically they should just add equal distributions of different colour-patterns of 'mons through the game. Or have a rare item that you can find/buy to change the colour of the chosen 'mon. As it stands it's just the colour equivalent of "Proud of its Power" and cutting it would probably filter a lot of autists from the playerbase.
