So according to people that attended the Legion panel at comic con SD (I didn't even know they were holding a panel) the Devs said that it's possible to turn into an agent of the legion/ dreadlord (like you can in the ptr) RIGHT NOW ON THE LIVE SERVERS. BUT the way to do so is hidden and no one has found it yet.
So guys, be on the look out for anything unusual and report it here so we can find out how the hell to kick this thing off.
