Not even 20 minutes ago I was running around outside of Limsa when I came across a "Rep" just standing there. She didn't respond to anything I did or said. She vanished before I got to take pictures of her gear, but she was a Rank 1 Gladiator. This was just outside of the Bearded Rock camp.
The entire time I've been playing through the Beta these last few months and exploring high and low, this is the first time I've seen something like this or even seen it mentioned. Thought it was pretty cool. I just wish it were daytime so the screens came out better.
