Kalgan chimed in on a thread in which the original poster insisted that Warlocks, despite dodging the bullet on life tap, still have a nerf bat incoming somewhere. He rebuffed the poster with a nice little tidbit that may intrigue Warlocks. He also ensures us that, no, he does not hate certain classes.
He says that they'd like to give Warlocks some type of escape or defense mechanism so that they don't have to balance warlocks around the idea that they'd be "tanking" melee classes in PvP. By melee classes, I assume he means Warriors, who can shake off a Warlock's main defense, Fear, with very little trouble in multiple ways.
He even brings up a spell that Warlocks may be getting in the expansion.
