Is there any power-up more useless than Night Warrior across all forms of media?

Like, it literally accomplished nothing.Tyrande received the ultimate power only the chosen of Elune can wield, burning away at her very life force for the sake of vengeance, and she...Didn't annihilate the enemy army in Darkshore, instead freezing a bunch of them in place temporarily and allowing Nathanos to escape.Finally killed Nathanos, but only when he was prepared to die and knew it was inevitable. Also when he had literally just fought off dozens of other powerful enemies so he was unlikely at full strength.Began to lose her sanity from the power driving her mad.Became a rocket by exhausting all of the power to tackle Sylvie out of the air and choke her briefly. Which I don't get because UNDEAD DON'T NEED TO BREATHE.Seriously, this is just the most blatantly bad writing I've ever seen in the game. It literally served no purpose.
