"Can't Touch This!"

Trivia
From the Nightfall skill preview (wikified):
 * This skill is named after the MC Hammer song U Can'T Touch This.
 * '"Without a solid counter to touch-type skills, we decided to add a new Paragon shout called "Can't Touch This," which causes touch skills used on friends within earshot to completely fail. This will allow players to counter skills like Blackout, Shock, or Vampiric Touch more effectively."
