Square Enix's RNG

[TomTom1968]

RNG doesn't mean if it's 25% chance that you will get 25% HQ by the end of a run. It means when you click on that node you have a 25% chance to get 1 hq. The next time you click, you have the exact same chance. RNG means that even in 1000 gathers, you could get 1 hq.

The same thing happens with a dice roll. It's completely random. Try it sometime.

That is how random works. Yes computers have pseudo-RNG but in the grand scheme of things it works just fine for a video game.

And dont't forget that the Human brain tends to forget about positive results more easily while negative results are remembered. I am also sometimes frustrated when I have a 50% HQ chance and don't get a single HQ item. But on the other hand, I sometimes have 3-4 HQ items although there is only a 15% chance. And everything below 100% can result in getting nothing even a few times in a row. Also, making 100 attempts and writing down the results doesn't lead to any useful insights because the next row of 100 attempts will surely reveal different results. That's what RNG really is. You might not like it but it is stochastics working as it's meant to be.
