More seriously though I'm not sure what to think of it. I thought initially that only Ultimates were content that should remain "pristine" and "out of time" (since they're basically fancy reworks of older content themselves and the hardest difficulty achievable). But now more content gets the same treatment like Criterion... or perhaps Chaotic as well. So what puts those apart from savage and extremes so that they cannot be unsynced? Genuine question.
