Are you kidding me with these rewards? The primary issue is difficulty, not rewards. You can still get better items in the open world, and guaranteed legendaries. How are you people just as dumb as the Blizzard minds behind this game? NMDs allow you to challenge yourself whereas the open world does not. Now, some of you are only nominally different from the brain-dead and perhaps you can be contented playing the open world in a vegetative state on an ironic power trip but that is a bad general recipe for gaming. Why is this so hard to understand?
