Zones I'm in... any/all of them. No bias. Even the Hallows. As I run I think what Travel power would fit best in this situation; Flight for cone damage, TP for speed, etc...
I like Croata, especially at Halloween time. Spotting Nessie, silent, slow, but eerie.
I like the scarred buildings in Boomtown, adds a tension you're not always safe here in the City. Just different/opposite to AP's look. I rarely go there b/c when I'm reminded of Boomtown I already out leveled it; exploration badges and screenshots. I think they should use it more IMHO.
