If u think it that way, yes, but on the other hand u pay 2800 gold and get 4 * 3 = 12 packs + for fun legendary and golden classic pack. When u do that comparison u value that 2800 cost as acceptable cost to pay. However, Zayle, Shadow Cloak, golden classic pack and experience of the adventure is valued worth 1600 gold / 16 card packs. Zayle, Shadow Cloak being golden makes it worthwhile also dust-wise but not by much. That being said, it might be still the most cost worth adventure-investment. Since one pack is equal to about 100 dust on average, you get that golden classic pack as a bonus.
