Why not both? 
Wait is this actually true? I know it’s fun to clown on Blizzard, but this is really sad if true.
I was checking out their Game Design and Art Internships posting, and it seems like these are their main posts:
Game Design Internship:
→ Encounter Design
→ Level Design
→ Narrative Design
→ System Combat Design
→ System Rewards Design
→ Quest Design
Art Internship:
→ Cinematic Animator
→ Character Artist
→ Concept Artist
→ Environment Artist
→ Gameplay Animator
→ Lighting Artist
→ Technical Artist
→ UI/UX Designer
→ VFX Artist
So I’m not sure how they structure things, but this should give a good idea of what kind of job postings they have. So I really don’t think it’s the case that they have 1-2 people doing everything. And this is not including things like Cyber Sec, Data Science, Finance, HR, etc…
Yes! We demand LESS variety!
