> Diablo 2 could erase weeks of work by one monster spawning an unfair combination. Only if you play Hardcore mode, which is entirely optional.
There is also an experience penalty on softcore in hell. 10% experience at lvl 98 is a few weeks of work for me.
Diablo 2 is a fairly forgiving and moderately casual game imo. Most builds require only one skill for damage, and respeccing and how easy it is to get a character rushed means it’s easy to experiment or fix builds.
