DE just doesn't know how to design a fun mode. Handicapping for artificial difficulty isn't a real challenge and isn't rewarding, it's just "wow finally that's over with." Before the daily reroll would at least give you a chance on getting at least 1 thing to work with something else of your choice, now you can just get complete garbage. It's either that or find a party that's willing to do 2 runs where one person just equips what they want, beat it once and then have them swap out their challenge loadout. Except a lot of leavers after that one run too, exposing the toxicity in the community.
As it is now, it's just a pure RNG mode each week to see if you only need to do 1 run, or if you're unlucky and you at the minimum do 2 runs where you maybe find trustworthy people to play with.
