This week's update is basically an admission by the designers that:
1. Their long-term goals are driving down player morale, player involvement and therefore company revenue.
2. They thought they could get people to play every 2 hours farming a single drop building (i.e. the Glimmergate) to get a chance at a rare drop to complete a long-term goal (Sister, Sister) within a 3 month time frame which turned out to be a vast underestimate since you simply can't force people to play every 2 hours. Instead they'll play as much as they can for a while, then the majority will simply get frustrated and delete your app.
3. Instead of admitting and fixing the underlying problem they're looking at this as another chance to monetize the solution by hopefully inspiring their waning playerbase to spend money while completing this new relatively shorter solution to their initial miscalculation.
