Dear Bungie Please don't lower the exotic drop rate when using a 3 of coins. I've used 40. Killed 40 bosses/ultras (Legit, not farmed) and only found 3 exotics. I could have just bought engrams from Xur cheaper, quicker, and with no work. The drop rate is not the problem. The cheese farming is the problem. That's what to 'fix'. Ed. Community consensus is a timer (like on synths) would be the best fix. Legit play is unaffected and cheese farming is stopped. Win/win bungie.
