This is the type of change I am referring to when inferring that AI may have helped develop the changes that enabled such a massive improvement over previous launch events.

I am not a Blizzard employee and don't have insider information. I'm just impressed with their improvements and hopeful it was at least partially enabled by their use of AI to help ideate, design and implement.

I don't think there is any evidence AI has helped them do this. They almost assuredly used AI, sure. But this seems like its the result of investing in their platform team and infrastructure over many years.

They've had layering for a decade.
