What kind bs is this

ive seen plenty of people say its not rigged or that the rates dont get lowered but ive been playing for years and i swear about 80-90% of the things ive farmed have had consistent drops DAILY up until the point that im about 20-30 shards away from being done, then ill go DAYS sometimes weeks with 0 drops.
Now If this only happened every now and then or if my drops up until that point weren't consistent then id agree its just RNG, but this feels like it happens way too often to be a coincidence or just bad luck
