>>25301293Notice I said non-legendary. Without shenanigans or autistic levels of resets it is nearly impossible to get a shiny legendary.
That actually has value unlike something you can grind with fishing or running through tall grass.
Bred shinies are almost just as good as legendaries because you're only encountering 5 over the course of a half hour with the same or half odds depending on where you get your stock.
Plus when you do get a shiny it will have anywhere from 3-5 perfect IVs and arguably could be used for real battle
