Say what you want and dismiss it as random all you like but you cannot deny how screwy it is.
Case and point: Why is it 80-89% chances are so prone to failure? Just today I failed Hasty Touch with Steady Hands II active every attempt (80% chance) in 1 synthesis 9 times! There have been multiple times where that same condition failed 3 times in a row, including during that synthesis. Constantly I am getting NQ results in that 80-89% HQ chance range. I don't care how two-faced RNG can be with both good and bad RNG, there should NOT be THIS much failure at such a favorable rate, not once, ever, in one sitting.
I think Square Enix needs to look over their RNG system because something is seriously not right... even if only by a little bit.
I should also like to take this moment to point out I haven't seen a 10k line in mini cactpot in at least a month now, and I used to see them often. Don't know whether it was nerfed into its now intended rate or what but just wanted to point it out.
