Diablo 4: 9 Changes Blizzard MUST Make
5. Prestige
Sinking umpteen hours into obtaining a single build-defining item isn't anyone's idea of fun. On the other hand, being handed endgame gear in an unending string of loot explosions causes any potential dopamine rush to immediately evaporate.
It's a fine line to balance, though one immediate partial solution to the problem is to not bring back Diablo 3's pinatas draped in demonic skin. Striking down Lucifer's legions and being richly rewarded with relics and gold is one thing, getting best-in-slot gear for killing a dreg is another.
Instead of making loot universal, restrict the rarest (and best) items to the upper echelons of Hell's hierarchy. Not only would the change encourage Nephalem to make repeated visits to challenging bosses, but - should the fickle mistress that is RNG smile upon you - be proof of your triumphs when strutting around town with a shiny chestplate only obtainable from a single source.
