I remember the day before the cataclysm hit Azeroth, people said that the tower of Quel’thalas most likely would be destroyed and gone or just impossible to reach cause of invisible walls. One of my favorite less known place. I spent the whole evening there, watched the sun set and took some screenshots you might remember. I really thought it was my last time there and it would be gone by the next day. Untill I yesterday flew around the Quel’thalas area and thought I’d check and I was happily surprised by the sight of the tower and everything else standing as it did before the cataclysm.
It’s harder to get there now, but I don’t know why they want to prevent us from going there as it is beautiful and even has an own chat channel. Hopefully they will fully develop the zone and put it to use in the game as they first intended.
