I was wondering how I should ever collect hundreds and, later on, thousands of Grim Favors to proceed with the seasonal quest and increase the Coven’s favor rank. How surprised I was when recognizing that many of the seasonal whispers provide 10 times their indicated Grim Favor amount for the quest’s purpose 
But if the whole calculation for the quest is off by the factor 10, why not just “correct” the calculation instead of exaggerating the effort requested from player like this…?!
