Nobody can host challenge lobbies just yet. Anybody claiming that they will host one is lying and fake. Trust me, TTG Moderators will let us know when the patch is out aka when you can get all of your titles, emblems, camos, etc. Be patient and don't fall for anybody's scams because TTG is not held accountable for your losses (ex: Loss of microsoft points, paypal, etc.). BE PATIENT!
