Also, I note that the game loves extremes. You rarely get the 80%, 6%... no, you'll get constant fails, until you've gathered 200+ of them and then suddenly you'll get 3 HQs in a row from the same 6% node without even using +HQ skills.

This is what is making me believe that the RNG system they use is terrible. You see this in bad RNG systems, where the computer will roll <20 on a 1-100 5 times in a row and then >80 5 times in a row, and then a bunch of numbers in the middle, and then give you five <10 in a row, etc.

That's the sign of a horrible RNG system.
