Well, since customer feedback is, apparently, not important, I'll have to express this here where it may or may not even be read. Occasionally, I use the Three of Coins during Taken events to get exotic engrams (who doesn't?). However, the last two times I have done this, using all five coins at once, I have received no loot; not even an antiquated rune. I even tried killing a champion once my coins were gone, and still no rewards for the event. That's two exotic engrams I could have had and 14 Strange Coins I won't get back.
