That’s the problem, its just your data, you don’t have a good sample or source, its just a personal opinion, as I mentioned before any RNG drop could be 99.999% drop rate that someone could be always hitting the 0.01% that doesn’t provide the item, its the same the other way around that’s why some cosmetics takes years and years…almost impossible to obtain.
Player power should be more deterministic with systems like Dinnar from Shadowlands season 4.
Example of bad RNG:
Neryssa from wowhead has been farming 1 trinket from Echo of Neltharion since June 26…still nothing, including vault, LFR and some other difficulties.
RNG being RNG.
