Stealth nullstone nerf?

the other day i got like, 12 nullstones in 2 hours farming (Have only maxed bismuth atm)

and today in the same time i got 0 nullstones, but got 7 imperfects.

Stealth nerf or am i just that unlucky?

I also have the impression that the droprate of null stones and imperfect null stones is lower than it was.

But beware that the drop rate for null stones and imperfect null stones is different. I got a toon with bismuth and ironclaw maxed out and I systematically get more INS than NS.

Anyway price keeps dropping, so soon mining the rares wont be so lucrative.

I have noticed the opposite (I got more recently) and thought the title was about nerfing the price.

I guess it’s RNG.

With NS prices dropping so fast (and nodes despawning so fast), I switched from perception to deftness.
