Yea I saw the video as well, but all supers can one shot kill a pike. Except maybe Defender...? I don't know if it damages anyone close to the dome or not. I mean, the Gun Slinger could one shot kill a pike with a pistol... from a distance. It might just be my personal build, but I don't see the warlock Sun Singer as a Assault build. I would rather use it as a team support build to boosts everyone's super really fast. I think that will be far more useful in raids and PVP.
