Bungie is 'looking into' the brutal grind for Wellspring drops in Destiny 2

Destiny 2: The Witch Queen is outstanding, possibly the best shooter campaign of the year. But it's not without its problems, one of the big ones right now being the extreme rarity of a particular type of reward drop that's required to craft new weapons.

You also need to hope that the Deepsight Resonance has a pattern which can be extracted, in order to eventually progress the associated quest. And seeing as the questline ultimately leads to the new class-specific exotic glaives, you can (possibly) understand why players are getting ornery about farming for hours but making little to no progress.

This video, from YouTuber Aztecross, breaks it down nicely: Regular versions of the reward weapons drop regularly, but the Deepsight variants are like hen's teeth.

It's not clear whether the activity is working as intended at this point, but there does appear to be
