Since I hit 450 before Ash and Iron I have basically been capped on Unstable Cores most of the time. With the supply drop I've purposely been spending as many Unstables as I can on gear worth upgrading and I still have over 500k of them, so I'm not able to pickup the 777,777 from the supply drop. What's my main bottle neck? Enhancement Cores. I've gotten down to 0 enhancement cores about 50 times since Edge of Fate released and there's no easy way to actually farm them directly. Even doing the blue armor trick isn't great because I'm spending enhancement prisms on upgrading the blues to get enhancement cores, but also on upgrading gear to tier 5. And thus I run out of those too. Using Rahool and Xur's weekly enhancement core purchases lets me upgrade a few items, but that's it and then I'm stuck with 700k Unstables and no enhancement cores. Since Bungie has already said they are deprecating Unstable Cores with Renegades I would like a way to convert those to more useful currencies, ie enhancement cores/prisms. For me personally Enhancement cores would be way more beneficial. I would like this post to serve as a formal request/petition to introduce this kind of system in to the game until Renegades launches.
