So we all know that Bungie has realized the three of coins glitch. They have hinted that they plan to nerf the drop rate when you use it. However, this is not the problem, the problem is abusing checkpoints. It can take anywhere between 5 and 10 sometime just to get one drop. Rather, here are a few alternate solutions to the problem. Feel free to comment your own.
-Make it so you can only purchase a certain amount of ToC each weekend
-Have the buff only apply to raid and strike bosses
-Make the buff increase/decrease depending on the level of the ultra (so no farming the level 14 draksis)
-Put a cool down timer between each use of the ToC, like how ammo synthesis works
