BD already copys their system so why not just go the whole 9 yards instead of a watered down version of it.
There is nothing original in D2 system. In addition, BD isn't the only game with that item system. "Watered-down"? I won't say. Just because there is a colour to the item it doesn't mean it was "ripped off from D2", agree?
For example, Degrade Quality is new to BD.
