Hmm, I can understand the frustration on that part. I had mentioned in another post of similar feedback that it might be better suited to throw in a weekly Pinnacle and some Bright Dust in there, in terms of rewards, Putting Cores and Prisms in there would take away from the Nightfall reward farming aspect (more so if you consider the Ghost Mod for Vanguard Nightfalls). But you still want something to entice players to do them initially besides a drop chance for an Exotic. I do know there is priority on the newer Exotics that get released, over the rest. So if any are missing from your Collections, then I'm pretty sure you won't be getting much until that condition is satisfied first. Once that conditional rule is satisfied, then like others are saying, keep doing the runs, don't die, run them flawlessly with Platinum Rewards (15+ times I'd guess) and see what happens. But thinking on that more, IF Lost Sectors are intended to be a source of Exotic farming, and are armor slot specific, then I think Bungie should also double up the number of Lost Sectors to choose from. Increase it from 2 to 4 so there's always a Lost Sector to farm for each armor slot. If Bright Dust was thrown in there as a reward, (a very negligible amount - combining that with the Vanguard and Banshee bounties, kind of gives that reward aspect for the Cores, and eventually the Prisms by proxy) Banshee bounties give the cores, Bright Dust could be used for getting those consumables in the Eververse store for guaranteed Cores/Upgrade Modules/More Glimmer. Just trying to think more snyergistically on this, without making it a reward copy of Nightfalls. ¯\_(ツ)_/¯
