Frostmaul E'ko not dropping

Group of 5, at least 3 attacking in every fight, confirmed that everyone was carrying the Cache. Killed about 30 of them, zero drops.

Bad luck unfortunately

Well, it’s certainly possible. Probability of this happening, assuming the historical drop rate of ~40% is correct, is about 1 in 5 million. Given the total number of classic servers and time with layers, you’d expect this to happen by sheer luck on the order of once a year.

Pretty sure normal drop rate is no way around 40%, more like 8% so yeah rng can hurt

It seems like the recorded data is not very consistent between sources, so you’re probably right.
