If we were talking about Blizzard of 15 years ago, yes, but no that’s not what’s going on here.
They’ve switched from min/maxing the player experience to min/maxing how much they have to uphold the player experience before it causes noticeable profit losses that aren’t compensated by other sectors of the company.
You’re talking about game design strategies, which used to be what this was about, but it’s more of an asset management strategy now. It’s industry midwits (thank Activision-Blizzard for their low wages for this one) doing their best to adhere to a concept of least expended resources for most profits.
