That’s functionally just blind faith written in a slightly fancier way and done in a way that’s completely unfalsifiable
The idea that when you see a massive amount of something across many listening posts and we have incomplete data that shows a particular thing you can just push that aside and go “square has more data than us so obviously they know what they are doing” even if stands in opposition to everything we can see. This isn’t necessarily about healers, this could also be about Kaiten, the viper changes or anything else “unpopular” they have done recently
Square enix can and does make mistakes and acting like they always do the right thing because they have more data (that they refuse to show us btw) is just so flawed and can basically be used to quash literally anything. If square came out tomorrow with a change you didn’t like I could just say “lol data, square knows more than you kick rocks”. May as well just delete feedback now since square knows so much
