Ok, but how much Blizzard is even left at Blizzard? lol
About 2 years ago I wondered the same, so I collected a bunch of data (of ‘who worked on which game’) and used D3.js to make a graph thingy:
Downside: It’s up to Shadowlands, not Dragonflight; Also, the few little circles pulled more left are mentioned multiple times in the same Credits, just under different roles.
The thick green circle is Customer Support (though this was before the mass-layoff by MS).
Live version here, but it’s SUPER janky - changing selections will generate a new graph lower down the page.
Raw JSON data here - I had to install Retail WoW (F2P is good enough), dig into the game files to find the .html files that contained the credits and then convert that whole pile of doodoo into JSON.
