Nope. I'm all up for not allowing flying mounts in WoD for more exploration and all but I think removing flight paths didn't help that at all, if anything it just made people want to spam dungeon ques more. At least I didn't bother to run from Org to Tanaris when I hit 40 because of zero flight paths available when I wanted to do something else besides dungeons.
They should change it back for Kalimdor/Eastern Kingdoms at least.
