I think like any other weapon in the game, it could have all the power in the universe, but if you’re not powerful enough to channel it then it’s not dangerous. As player characters, we are essentially avatars and not supremely powered beings. I mean, priests can levitate, but they can’t yank the sword out of the planet. An evoker can disintegrate things, but they can’t take out an entire city. Probably just a power level thing. Even Gul’dan who had the biggest sip of green Kool-Aid in history, still eventually got wiped off the map by something bigger.
