Item Rating(potential) and Enhancement(star) System

Which means, presumably, that the higher the quality, the bigger the pool is to choose from. And I'm not sure what was asked here:

- Each attribute is independent of the others when it comes to rank. You can have +9%/6%/3% (unique/epic/rare) on the same lvl 80 item at the same time.

But +9%str, +9%str, +9%str is possible.
