That's great, in theory, but here are a few problems. By forcing people to do that extra step, you risk getting a biased return. How likely are you to take the time to take a screenshot and send it to me when you received 12 Ass Energies? Probably not likely. So for the most part, I would only receive screenshots of exotics and holy grails. Also, there is the question of logistics. Who would enter in all this information? It's only Wednesday, and there already over 5000 submissions into the poll. Fortunately, or unfortunately, I am a Structural Engineer (bridge desgin) by trade, and don't have the luxury of time to enter all of those things myself. Now I have reached out to Deej asking if nightfall drops is something they track (they seem to track everything else that happens in the game so why not?). I haven't heard back yet, but I messaged him yesterday. Doubt I'll ever hear back, but if this thing gets enough attention on Reddit, Bungie.net, and elsewhere, who knows?
