On this note, there's an entertaining scammer accusation going on right now. Someone IDed 22 torches and is upset about no lock torches. The odds were even better than your case, a little over 5% of that happening. I have no idea whether it was a scam or not, but it's pretty crazy to get accused of a scam over RNG.
https://forums.d2jsp.org/topic.php?t=108525845&f=250It's funny cuz he claims he got 8 warlock torches out of the 25 torches he previously bought.
The chance to roll 8 out of 25 is 0.67%
Much lower than this 5% chance of not getting any out of 22 (5.3% actually)
So he should be accusing the guy who sold him those 8/25 lock torches, cuz these odds are so improbable that this look more suspicious to me
