1. Blizzard's Approach to the Spiritborn Class in Diablo 4:
- Blizzard wanted the Spiritborn class in Diablo 4 to be more than just a "pet class" where players outsource all the fun and action to their summoned companion.
- The developers aimed to create a class that allows players to actively engage with their spirit companion, making decisions and strategizing alongside it, rather than simply watching it do all the work.
- This design philosophy was driven by Blizzard's desire to avoid creating an "MMO-grade pet class" and instead offer a more dynamic and engaging experience for players.

2. Balancing the Spiritborn's Abilities and Playstyle:
- The Spiritborn class in Diablo 4 is designed to have a unique playstyle that blends the player's actions with their spirit companion's abilities.
- Blizzard wanted to ensure that the Spiritborn class felt powerful and impactful, with the player actively contributing to the combat alongside their spirit companion.
- The developers worked to strike a balance between the Spiritborn's own abilities and the capabilities of their spirit companion, creating a synergistic and engaging gameplay experience.

3. Feedback and Player Expectations:
- Blizzard acknowledged that some players may have preconceived notions about "pet classes" in games, often associating them with a passive and less engaging playstyle.
- The developers aimed to address these expectations by designing the Spiritborn class in Diablo 4 to offer a more dynamic and interactive experience, where players actively participate in the combat alongside their spirit companion.
- Blizzard's goal was to create a class that would surprise and delight players, offering a fresh and engaging take on the "pet class" concept in the Diablo franchise.
