They should have them all available at all times, the rotation is fucking stupid imo.
It's not an "argument". Keeping the MAU numbers up is their legal responsibility they took on when they became a publicly traded company and decided on MAU as a metric to show their shareholders how many people are playing their games after they switched from active subscriptions(because most of their games don't have a subscription). It's not some far reaching conspiracy. It is literally their job.

I feel like you don't know what RNG means.
lol it's not their legal responsibility to keep MAU's up. they won't be arrested or sued because MAU's drop suddenly. maybe you should look at what the word 'legal' means; I mean you're not wrong when you say it's their responsibility to keep gamers invested in their game, but is it a legal responsibility? no, no it is not.
