Sunset DC weapons can still drop to complete your collection albeit more rarely. [quote]We are making these changes to help preserve the relevancy of the destinations, specifically some of the pinnacle end-game activities that still exist there. To get more specific around the actual experience, activities where re-issues are acquired will be heavily weighted towards rewarding re-issued gear over capped gear -- though the exact weighting and mechanisms may differ. For example: In the Dreaming City if you have already obtained an infusion capped weapon, it will not drop for you again. [/quote] https://www.bungie.net/en/Explore/Detail/News/50006
