Specifically Wrath of the Machine style. Unique perks and combinations. Set rolls so the weapon has an identity and you don't RNG on top of RNG. I still remember the names of those guns, fatebringer, visions of confluence, corrective measure, black hammer, genesis chain, ex machina, steel medulla, chaos dogma etc I can barely remember the names of the loot from the last raid since its all the same as "random legendary gun A". D2 has some incredibly sexy designs for its raid weapons, its too bad that's the only thing really special about them anymore. TL/DR Maybe raid gear would be more valuable if it didn't have the same or worse random rolls than gear that takes far less effort to get. Why does the stuff I get for holding X in the tower have better rolls than pinnacle rewards.
