Great game just one request

So far the game is great aside from being locked out due to speed limit and some loading problems. My request is please up the spawn rate for Unown. Its one of the last ones I need and I havent seen one. Ive seen more Blissey (Only one tbh but its still one of the rarest things out there) than Unown. Im pretty sure Unown is one of the most common Pokémon in all of the games (In some areas at least) How are we supposed too get the reward for registering all 26 forms if just one is insanely rare?
