Yeah, upper B-list, but still B-list, I think, like Escapement or Armada. Get them on a villain team with a halfway effective coordinator and they'd be much more dangerous, but the average hero won't have much trouble if they have any idea what they're doing - as you say, Impulse is effectively just a (or two or three) punk with a gun, when you get right down to it. An assessment they assuredly loathe with ever fiber of their wanna-be upper crust beings, naturally.
