[b][u]How three of coins should function:[/u][/b] Your rate of exotic drop stacks increasingly every time you do activity until you get an exotic, then it resets. Example 5% base drop rate of an exotic in a heroic strike. If the end reward does not gift you an exotic, the next time you do one it's 10%. The time after is 15% and so on. This means you are eventually guaranteed a reward for your time, but it may drop sooner based on chance. Done. I fixed your game, Bungie. My advice is free. To anyone who thinks that makes exotics too easy to get, you fix that by leaving some exotics in the loot pool, but others come from specific events like quests or raid bosses. Done.
