Sephuz activator in macro

Hi all,

Just looted sephuz as my second legendary, as a stat stick it’s an upgrade. I’m wondering if it’s worth integrating a conc shot cast into the macro I’m using. Raid bosses are immune making this kinda worthless?).

Equip: Successfully applying a loss of control effect to an enemy, interrupting an enemy, or dispelling any target grants you 70% increased movement speed and 25% Haste for 10 sec. This effect may occur once every 30 sec.

It wouldn’t hurt with world questing and most dungeons but I wouldn’t for raids or Kara where you have fights that benefit from rotating interrupts among the group.
