Imho, frustration comes from that adventure packs are very tightly connected with gear incentives. This puts the largest reward system in the game into a really dark little spot, that is mainly leveling gear for new players. Yes, the legendary & mythical new players

Anyway, last time a coupe of us suggested a revamp, and is what brought us here, tho not because we wanted it to be like this

. Credit goes elsewhere

I would personally very much like to see "life" put back into rand loot, much of the replay value sink is there, the "treasure hunting" experience , or lack of it , largely adds to why some players arent "just running content for fun", altho at first that might seem contra logic, but a lot of other games thrive using a better rand reward system, some even put the highend stuff in there at 1:10000 chances and cool stuff along that curve.
Chest runs anyone? No way unless there is some static loot in there
It really does not take too much fantasy to make rand loot at least viable, next to named gear. Or even include some generic sets on rand loot that goes halfway if you manage to luck out a good set with decent affixes.
From 20+; Sentient weapons pretty much nulled anything coming from randgen.
