Diablo 4's Limited Playability and Path of Exile's Combat Comparison

Diablo 4's Nightmare dungeons will scale beyond level 100, but there is a limit to the game's difficulty. Players will eventually face a "pinnacle boss encounter" that'll test the limits of even the best level 100 builds. This particular boss isn't designed to provide powerful loot, it's about giving players a sense of accomplishment. The encounter will take several tries before having a chance at beating.
