There's an element of truth to what JustMonika says. This spell is only dangerous if you've casted every single spell on the book on yourself. The difference is, before, with all that kind of magic on your character you were virtually untouchable by any means. All your detection stats through the roof, empowered attributes, premonition, spell resistance, every stackable spell on top of each other. Now you are vulnerable to one thing that can counter that, if you decide to go over the top. So you have to be more selective with what you cast, and balance things out. Or take the risk.
