I suggest the following drop chances for Stygian Stones depending on the tier X of “The Pit”.
f(X) = (X^2)/(200)^2
In my opinion this would be more appropriate, because very low tiers should get very low drop chances and very high tiers should get very high drop chances, and since the difficulty is increasing non-linear, the drop chances should increase non-linear too. My suggestion leads to the following table of drop chances for Stygian Stones depending on the tier of “The Pit”.

Right now the probabilities are
Tier 1: 5 % (way too high)
Tier 40: 10 % (too high)
Tier 100: 18 % (too low)
Tier 200: 30 % (way too low)
With my suggestion the drop chances would be (rounded)
Tier 1: 0 %
Tier 40: 4 %
Tier 100: 25 %
Tier 200: 100 %
Especially given the latest changes of The Pit in Patch 1.4.3, this would be more appropriate drop chances for Stygian Stones! Especially if you manage to finish the highest tier 200 of “The Pit” successfully, you should get a guaranteed Stygian Stone, because it is difficult enough. The drop chance of 30 % for a successful run of tier 200 of “The Pit” is ridiculously low. Compare this to the drop chance of Stygian Stones at world bosses, where you don’t even have to fight, because there will always be some players who basically “one-shot” the world boss in a second and then you get a Stygian Stone with a quite decent chance, but with nowhere near the effort you would have at the current tier of the pit with this drop chance.
Please, Blizzard, implement my suggestion. Thank you.
