I would like to suggest changing the graphic for Suffle to match that of Elude. When stacking multiple aura's, (i.e. Boundless Storm, Green Dragon's Blood, Shadowy Disguise), with Shuffle, it's almost impossible to tell that the buff is still active, if one of the other graphics is on top. The graphic for Elude, on the other hand, has a glowing, white orb in each hand that leaves a trail as you move. This is much easier to distinguish when running multiple auras.
Changing the graphic for Shuffle, to that of Elude, would be the easiest way to solve the aura overlapping issue.
