Hello,
Looks like this class now have it own island Probably we would need todo something on this island for completing special lock quest-line that comes in patch 5.2. I just post the screenshots that you can see (again keep in mind this can be diff with extra environment decoration):
Update:
It is not one Island, it's a damn Warlock Area, as you can see on the image:
Again those Warlock gonna sacrifice some innocent man that is standing in the middle of the pentagram
Keep in mind this is RAW loaded files in 3DS Max, and it WILL be much more pretty In-Game! There are some models missing, I couldn't record you guys the full tunel, but I give u in the end some images. I just manage to get you out Those 3 interesting islands.
Question: Why are there Alliance and Horde Portal???
Also here is some Interesting Doodads, Jaina made a Dalaran Eye that is watching u, a really cool Warlock Island Door, new culture of Zandalari and in the end Dalran Tower. Interesting with Dalaran tower is that there is some phase like we gonna need to make this tower by the models in the files. There is phase 1, 2, 3 complete 1,2, and in the video is final version. So this is just speculation by my side from file names
