I'm not sure if this is 100% true or not, but earlier today after the maintenace (please forgive me if this has been posted already), a friend of mine that had bought retrace for use on his friends (couldn't quest it because he didn't have wotg installed) tried using retrace on whitegate on some guy that was shouting for it. But when I retrace'd him, it worked fine (I have wotg).
Anyway know if they ninja'd it to make it so that you have to have wotg or something?
