Ammo finder is a module that is added to the code, it’s not embedded in the original design. It acts in competition with other modules, very much like a captain’s teleporting defend module when you’re too close to it takes over the overload stagger module, since the former is actually embedded deeper in the code. On top of that patchwork design, there is yet another condition superposed to it: using an exotic primary to get kills. That’s not to mention the fact that it fights yet another, deeply embedded coding: normal heavy drop. Hence you have many layers competing, and the game just can’t handle it, leaving you with small bricks dropping every 40 or so kills with an exotic primary, assuming you get the kills. Thus you’re much better off avoiding all that messy coding altogether, and instead running double special without ammo finder mods equipped. That’s because deeper in the code, the game is designed to drop bricks for stowed weapons. The less variety, the more probability the game will drop bricks for the alternate archetype. At this point, you don’t even need to get weapon kills to have ammo drop, just switch to the weapon you don’t want ammo for and go abilities. Not only will you see many more bricks (both special and heavies), but these bricks will, unlike the ammo finder ones, yield actual ammo, and not ridiculous things like 1 LFR shot with scavenger equipped. Bungie probably worked long and hard to find a solution to this issue they must know better than anyone, and eventually resorted to bring… Cenotaph! The down side? You’ll eventually realize that the only real challenge in this game is the ammo economy, especially with Div + 2 aggressive players spamming heavies. A realization just as old as VoG D1 gatekeepers minos. It seems obvious to me that the exotic mission tormentor fight was designed with this approach, especially when you realize that having all three players remain stack to go around the map and kill the Minos actually works better.
