I've been playing my Sym/Nat controller a little and every time I hear those powers go off I just think "Damn, this would pair so well thematically". I'm not so sure however, how well they'd actually do either on paper or in-game. Even if it just ends up being so-so I'd still love to give it a try. Could someone spare a little time to come up with a build worthy of the legendary Siren?
