Think about it, it is aquatic by nature and has tons of nagaz.
The zone is very beautiful, the music is astonishing, and the attention to details that was put in there is quiet remarkable.
When I saw the introduction cutscene I thought this was going to be Vash’jir 2.0.
Then the disappointment came. I kept hoping Azshara would collapse the oceans and we will get underwater magic spell to continue our journey.
Naz’jatar being a huge maze for me to travel does not make this thought just go away. Everything is so scatter.
Oh, and if it was underwater we probably would not see that abomination jumping jelly fish WQ.
So yea, it should have been underwater zone, huge missed opportunity IMO.
