No joke, my buddy has a 5 year old son who is fascinated by Destiny. He was running crucible the other day, popped his Spectral Blades, and handed the controller to his son. Little dude got 3 kills just mashing away at the buttons. Skill-based pvp, lol? Currently, there exists no counter to Spectral Blades. None. If you're ahead on points, best option is to just suicide yourself to preserve the win.
