I have been that person who fully melded a ring on the first try and hit that 7% meld for a friend on the first try. I have also been that guy who failed for an hour on something that was almost a guarantee. I can't tell you if the Random Generator is truly random because I don't care to spend the time to do a Monte Carlo analysis or Anovas based around the supposive seed conditions, but I can tell you that I think basing the game on as much range with low probability of success is a pretty shitty design. If Alex drops at 1% from fates, then I much rather need 7500 Alex and make it 100% drop. The Deviation around such critical low drops is just not fair to the player base when there is not enough content to smooth out the experience from player to player.
