Bastion for the visuals and music, less so for the brainwashing Kyrian. Just wish the zone was bigger with more variety. But I am so happy Blizz went for more mood setting music this time around instead of the overly epic we have had since WoD. It gets tiresome after a while but these new calm tracks are what I fell in love with WoW's music originally.
But Revendreth gets a huge plus in my book for absolutely nailing the gothic theme and for how big of a scope all the buildings have. It feels massive and intimidating which fits the theme of the zone well.
Ardenweld is pretty but apart from the Pandora vibes it doesn't give me much.
Maldraxxus is just a pile of poop and bile. Abolutely hate this place. Same with the Maw.
