I've continued working on Korthia. I'm not really farming anything, just casually doing dailies and the Maw Assaults.
The first Assault was Ardenweald. This was pretty good for the most part. The sneaking section was a little weird because other people were in there with you. There were a couple times where someone else redirected the searchlights right on to me.
The second Assault was Revendreth. This one was a bit unusual because it had a kill 30 mobs quest combined with a "feed corpses to a critter". But then there were two other "vehicle" quests where you couldn't activate the critter, but could still kill mobs. It wasn't too bad, but it kind of felt that the quests were fighting each other. Like you didn't want to kill too many mobs while in a vehicle, because you'd have to kill extra to feed the critter.
Also the last boss of the Assault must have been terribly annoying if you didn't have an SSD, as there were 8 loading screens!
I also took a couple of alts to Korthia. The skip is really nice, taking you right to the dailies.
The story is getting a bit more interesting too, with the introduction of the Nathrazeim. Be interesting to see where this goes. I hope it doesn't go too far into "The Jailer was responsible for all the the previous Evils in Warcraft!" It's already pushing into that territory with the Lich King and the Helm of Domination and Frostmourne.
