These changes were about balancing monster difficulty vs. monster reward. It also helped us make sure that we weren't making any zones in Act I, Act II, and Act IV too OP, or the next must-go-to place for farming, by increasing their density. This way, zones should be more even in terms of reward, which should in turn give players more options when deciding where they want to farm.
