There were a handful of obscure areas, yesh. T'is nice to have a reminder of 'em, though!
My all time favorite area in WoW is uninstanced ZG. Every person I've ever brought there has fallen in love with it instantly as well. Not much real RP potential however.
So much potential for it Belth! Like... like... TROLL KINGDOMZ! :3
I've tried, multiple time. Both on retail, and on... Well, four different private servers. It succeeded on Epilogue, the precursor to Prologue, but never received much support otherwise. I'm thinking about having Thraze squat there however, since the Atal'ai have been run out by the Horde and Alliance respectively. However, we've veered extremely off topic.
