I'm intrigued!
Unfortunately I can't try this out right now because I'm deep into Horde territory trying to fish Old Crafty and I'm not leaving until it's mine (I'm about 1500 casts in, RIP my dailies the last 2 days). I've also vowed not to use dungeon finder until I've soloed every 20s dungeon (I like to put rewards at the end of my goals as a driving force) and I still have about 4 expansions to go because I've been focusing on fishing.
I'm curious how flying from Ironforge to Zul Aman suddenly teleports you to Quel Danas NORTH of Zul Aman, though I've never gone back to Zul Aman since I got the flight path and the flight there has probably always been that way.
I think it will also feel weird to go somewhere that didn't involve shooting myself out of a cannon, pushing a raft for miles, or climbing a mountain as a ghost.
Either way, good job finding this! I'll get there someday... *cries in raw fish*
