Scope is bugged, here's torment?
This also came to my mind when I heard about torment a while back.
I believe the devs never actually stated that scope was bugged because it was hard to get the game engine to recognize whether or not someone was standing still, we all just assumed that because it was non-functional for so long and then got changed instead of being fixed. I don’t think we were necessarily wrong—my guess is that it was just easier to change it to the 600+ distance version than to fix the original version.
Nobody said why it was bugged, that I’ve seen.
They didn’t even know it was until people started doing 10K-shot challenges.
A month or two later, new Scope.
