Ok...let me level with you here SE...

except 1 person cant exactly kill 5 DL's solo, its not exactly a pushover if you're alone. You'd also have to consider the bottleneck of this: theres 15 places to get DL pop items, which have to be lottery spawned, in a time constraint area, and then theres only one DL ???

20 umbral marrows where 1 can drop from regular DL, and a pouch of sorts containing 5-15 from ADL so larger groups can plow through shit. OK!

You can't solo 3 PW's. You can't solo Rex or Ig-Alima. Hell, you can't solo Animated Weapons or Attestation NM's.

Yes there would be a bottleneck but the items would also be available to buy for far cheaper too.
