Edit 2: so how are these changed. Is stacking using multiple before bosses, between them, or both reduced within some timeframe [b]Edit3: this is my best guess I hope it helps. 3 of coins now has a stacking reduction cool down on it. So multiple uses both before and after ultras are less effective at stacking drop rate. Using one before an ultra and not using a successive one until youre at the next ultra after about a mission or strike has passed is how it should be done to avoid using a second within the unspecified cool down. I doubt bungie will release that time frame to avoid more cheesing[/b] Edit: to those who don't know bungie already said they will be changing three of coins and specifically the drop rate is too high Dear bungie, Please consider changing the availability of 3 of coins rather than the drop rate. The most infuriating thing about these types of items is the perception they don't work or that the drop rate isn't worth bothering. Right now the rate of drops to use is good about 1exotic every 4 or 5 on average for me using one or two at a time. This feels rewarding and worth my time but I don't need to be able to buy more than 5 a week
