Responding to this CC reply here:
Was Timeless Isle’s primary objective to tell story? I don’t think so. Its primary objective was…to kill rares and farm currency. Mechagon served much this same purpose, with its campaign being quite the footnote of the zone.
They’ve shown in the past they have an idea in mind that isn’t always story when it comes to these zones. Zaralek tells a story but was also implied to be endgame content; story-focused content hasn’t been “endgame” in a very long time. So it stands to reason that when Blizzard makes the zone have a very farmable ecosystem for currency and the like but then comes out and says “this wasn’t the primary objective of the zone”, people are going to scratch their heads.
