Netherstorm is just sick. Some collections quests? Sure, but they aren't bad and you are usually farming useful stuff in the process. Do the Area-52 quests, hit the Ecodome, do about half of Stormspire then move to the Kirin'Var Village. Finally, be sure to hit the small consortium settlement in the Southeast. You can do a few super easy, big xp quests and get some nice blues in the process. Plus, if you want to do the Eternium Prison Key bit it's there too. I went from 68 to 69.74 in one day there (post 3.0.2). This saved me from doing the collection quests in SMV so I went straight to the Gorefiend quests (almost straight).
