I love the way Tanaris looks, for me (out side of the mountains) it doesn’t have the feel of a warcraft zone. The very light color sand, the very light blue sea. For me it has a different feel because of that. Quest wise there really isn’t much in this zone, a lot of it end up being empty space that could of been used differently.
But there a lot of lore, Southern Kalimdor seem to be filled with more Titan ruins than anywhere else Wow, but not much is explained with this zone.
Overall i’d pick one of the other zone over this one.
