Not a dev, obviously. But there is literally zero chance that any dev will divulge that information publicly. You’re asking for confidential, privileged information that protected by NDAs. Beta testers don’t get this information either, nor will they ever.
Sometimes, I wonder about the context of that statement. While that statement was absolutely made on-stream, I don’t believe it applies to people that post on this forum as we are not “average” gamers. The average gamer is likely a casual player.
To that extent, the 26 game statement could be interpreted differently. For example, multiple posters on these forums believe that this statement means that Sirrian believed that players are playing too many matches. Another possible interpretation could be that Sirrian pondered that the average casual gamer was needing to invest too much time into matches to make the intended casual-level advancement per day, which could have been potentially reduced for casual players via new microtransactions in future updates to speed up casual player progress.
Personally, I do not believe that the 26 games per day statement has any relevance to late or end-gamers at all.
Again, not a dev, here. But, as someone who is experienced with many gacha games over a long time period, the broad trend of how gacha games tend to operate regarding end-gamers tends to hold here. Self-sufficiency in combination with full-completion of end-game content are the antithesis of gacha games. If an end-game player can clear everything by themselves, then there is no reason for them to make any purchases. This is bad for business. As long as end-game players can keep clearing the highest walls and the can handle the highest loads of required effort, those walls will continue to get steeper and the loads heavier over time.
QFT. How many times on these forums have posters vigilantly proclaimed that after the some previous new faction weekend, that they would never go through the time and money madness of clearing a future new full faction event? Yet, these same players are often here making the same proclamations month after month while “only” buying Tier 7 seven to ten times for the following month’s new faction event? Yes, these purchases could have been made purely with passive income with no actual real currency changing hands. That doesn’t make the situation or this behavior any more palatable for those individuals.
