This is a realy good idea community wise and I'd support that. I can also see that with the features you presentated this should work like a charm !
However, my concerns are as followed:
- I feel it will be unnecessary to display Common Shinies, as most of them are insignificant and will create spam. On the other hand I have no issue with Uncommons and Rares.
- Will every Pink be displayed like Shadow Pokémon ? As you know Pink Pokémon are H24 huntable as opposed to Shadow Pokémon. For this reason I think only Uncommon and Rare Pinks should be displayed and also because of the 1/1500 chance for Pinks that would lead to more spam.
