I just thought I'd put up a thread that would show all the spots I've been able to get to so far. These are only the ones I feels worth mentioning and I had fun getting to. None of these are on a private server because I personally think that if I can't find it on a live server then I don't deserve to see it.
Under Outlands
Netherspace
Thralls Room Drapes
Corner of Azeroth
The Pit of Criminals
Well of the Forgotten
This next one I had a really hard time getting to lol.
Abandon Goblin Factory (not sure if that's it's name, I just called it that)
