Another whinge about stygian stones

As per title , 3 of us do a lot of higher level pits at around lvl 90 and in the past few days have got only like 3 stones. Surely this is not intentional?

My estimation based on recent experience is that stygian stones probably have about a 5% drop rate which is rather low.

  • The chance to receive a Stygian Stone on completion of the Pit has been increased.
    • Examples:
      • Tier 1: 5%
      • Tier 40: 10%
      • Tier 100: 18%
      • Tier 200: 30%

Must be my bad RNG, ran 10 lvl 70 pits and not 1 stone today.
