Yeah, I get that. But the devs know what their average API calls are per user, seems like they would have landed on those numbers here; less frequent users likely subsidize power users to some extent. Or, like reddit, they could price it dynamically based on your usage too.
But you also might be right that it’s only affordable if ALL power users moved on. Probably fewer moved here than we’d hope/expect, but I’m sure it helped.
I’m not sure if you have checked out WoW lately, but it’s actually a pretty beautiful game. I think generally they want the tech specs to be a low barrier to entry for a game where they want millions of players playing concurrently. It also cannot be super heavy or things like raids and battlegrounds would chug.
