Yeah, I was having hate issues in a party that lacked DD once and decided to try it around Lv.65 or so for the heck of it. Ironically, all I did was pull hate with it too... I imagine it lowers Cumulative hate with it's effect, but still gathers both Cumulative and Volatile hate from dealing DMG. Meaning it may actually lower your Cumulative hate by a small amount, but it raises your Volatile hate enough to still pull hate.
...In summary, yeah, pretty much defeats the purpose anyway.
