The brain shutting down is yours. I'm all for other methods of etheric light. The current is way too restrictive. But to be legit, these new avenues can't bypass DLC. For any game with DLC, the devs design it to be painful to play without purchasing. In this case, getting max-level gear and guns is supposed to be next to impossible without HoW. By allowing you to purchase them with marks, you make it easier to get max-level gear (I'd much rather hunt for 200 vanguard or crucible marks than any current method for etheric light). In short, any new reliably replicable method for etheric light will never be available outside of the DLC. Occasional RNG blessings: sure. If you want to brainstorm new etheric light paths: please do. It's in short supply. But these paths have to be something Bungie is willing to do (that makes financial sense for them as well).
