Except berserker powers come with huge, enormous, get-you-killed drawbacks, and are also powers which can be prepared against, defended against, reduced, and generally circumvented.

None of that can be said about this particular scion power. It's entirely without drawback and it is impossible to defend against by most of the people who are required to fight the cabal. Worse, it renders a success against all the scion actual players a loss.
