They should let Orr get progressively greener with each major update, as we drive out the undead and new stuff comes up.
Orr is an ugly place full of ugly mobs that do ugly things. Which is intended, but after hours and hours you kinda feel like one of those rotten things yourself.
If not for the fact that it is ugly in a very post-apocalyptic way (which, I guess, makes it somewhat cool), I would've skipped it all together for Frostgorge on my 3rd and 4th characters... Such a depressing place! Which, again, means that they did a good job... But it's time to end the madness! The ugly mobs should go, they were good at doing what they were supposed to do (being ugly, that is) and now that we've killed Zhaitan, we should be rewarded with cute things in Orr. After spending so much time there I'd much prefer to fight cute things that one shots me. Something not brownish green. It's a crime how much expired meat I see hanging around everywhere.
