I hate how Game Freak does ass pulls like having Regi temples in Unova and Galar just so people can obtain legendary Pokémon without having to transfer them from a previous game. The Regis belong in Hoenn and Regigigas belongs in Sinnoh. Lore should take precedence over accessibility. So what if there are Pokémon you can only get from transfers? That's actually a good thing because it makes the Pokémon more rare and special to have in your collection, and completing the Pokédex becomes a more daunting achievement.
