More on Warlocks in the Expansion

[Lissa]

They can do it far more efficiently than any other class, and Stone Warders aren't exactly difficult as far as elites go. They have a lot of HP, but they don't do much damage.

Go solo demons in Winterspring like I've seen Hunters and Warlocks do in the past:)

I dunno, I've seen some Frost Mages take things apart far more easily and efficiently that a Hunter or Warlock will ever do. Likewise, with a Shadow Priest, if it's fearable, it's killable and this can be done just as effciently as a Hunter or Warlock as well.

Efficiency has more to do with your skill as a player and your spec more than a class issue cause I've seen a number of badly played Hunters and Warlocks that couldn't kill an elite several levels below them where a skilled Frost Mage or Shadow Priest takes apart even con or slightly above elites with nary a scratch in a fairly quick manner.
