It's been said before here, by Xz. DS magic has serious potential in the sheer magnitude of power a person can wield. Acnologia and the other Dragonslayers from centuries ago are a testament to that. It is "so freakin' powerful", it's just that we have yet to see anyone in the current time period use it like that barring Dragon Force moments (and it's really only the fight with Hades, tbh) with Natsu -- which are more just one-time powerups to ensure a win fo the "heroes" of the story.
