I think it coz it has special effect attached to damage dealing, i.e. same rule as AOE caps for skill where special effect can affect only 6 players or more if skill is "rulebreaker".
Guess it too much work to implement for just 1 set to forcing calculate how many, from whom ,etc. it should drain.

A better buff would be to give it some single-target power back. Double damage on the closest target would work. They nerfed the damage to make Auroran look better but it left the set neutered.
