One of the types a lot people expect to be real one day is the Light-type, to be the polar opposite of Dark-type. So the inclusion of this type was a no-brainer.
However, Light-type is more than that. In Azurite, Light-type focus more on support and recovery. While there are still enough offensive options for Light-type Pokémon, you'll find that their niche is more based around supporting other Pokémon or themselves, being unmatched in the recovery category.
