Your favorite spot.

My favorite spot, as far a specific spot goes, is in St. Martial where the "Dead Man's Tree" badge was.  If you angled your view just right you could see the hanged man.  As for a zone in general, I'd go for the Storm Palace, with a couple of the other Shadow Shards close behind.  Oddly, while I enjoyed exploring there, I didn't enjoy the TFs there, or missions in general.  Too much time spent in transit.

I liked "hiding" on top of those walls inside the train station.  It felt like we could go anywhere and do anything, when you could stand someplace like that where there was no logical reason to be there.
