YES, I love chaos.
IDK, it's whatever
Chaos = more enemy spawns, more random events, harder patrol missions, just more chaos (ex. Alters of Sorrow event on the moon).
Long ago when they showcase D2 for the first time and mentioned Flashpoint, I thought it would work like world tier, where the entire planet will get more and harder enemies, different type of public event, etc . I was disappointed.
