Woot! (which actually means we owned the other team, but I'm using it to cheer)
Glad to see there is raid content for those that are lower than 50. That also brings in a sense of danger when crossing a zone, which, in my opinion, is severly lacking.
Aspiring guilds and groups can do the big-boy stuff without having to actually be one!
Oh, to finally answer the question, no I haven't seen it. Wish I could, just so I could test agro range and then turn and run, screaming all the way to zone. :)
If I remember, the location is near the camp that starts the Condemned Catacombs quest.
