21 strange coins, which I will use to buy 15 three of coins, which will result in at least one if not two exotics. Given my RNG, they will both be Hereafter. Is that the kind of reward they intended? I don't know, but I don't play any RNG game for the loot. I play for fun and the loot is a side benefit. Basing your enjoyment level on loot in an RNG system sounds like a recipe for frustration.
