Nightmare Raid Chests no longer scale

So I have a main account (valiant) and two alt accounts (paragon). Main account I actively play, alts are mostly for auto questing. The exception to that is mainly raids, I have all 3 accounts participating in our alliance raids and we did try nightmare raids. Previously in normal raids, they got a "Paragon chest" not the generic basic chest. But currently in the Nightmare raids they got the generic chest (which contained 10k 6* shards which is essentially useless). Why do chests no longer scale in Nightmare raids?

So if they all get the same rewards, weaker players benefit a lot more than the stronger players
Apparently Kabam hates that
