I did a couple arenas before the server reset an hour or so ago and I noticed that the ghostly ego lady was standing there next to a highlighted spot to exit the arena. I've never seen this in the arena upon the match's completion before. I hope some of the Thorn ideas some of us have been jabbering on about will be implemented.
If this is blowing the whistle on anything, someone official could pm to shut up about it while bugs are getting worked out.
