Your wish is granted—al other sources of upgrade materials are now gone and they come exclusively from bounties. This is Bungie we’re talking about. Be careful what you wish for. (:

If they tuned it right (and didn’t reduce drop rates from other sources), I could see that working. I feel like would have to reduce normal drop rates from normal sources to get anyone to care about that though. I’m drowning in Enhancement Cores. The higher level ones are obviously still rare, and I wouldn’t mind seeing a Weekly bounty reward at least Prisms.

I’d expect that there will be a significant reduction of both investment and reward from bounties, but insofar as it still keeps enough value for those people who like doing bounties. Would be nice if the weeklies were focused on being a Bright Dust source first at this point. And reduced the time investment to make it easily completed during activity weeklies to help sate people who think they are too involved already.
