WoW dev was surprised that players 'like being jumped' by the upcoming Prey system—even on its hardest difficulty, where 'going AFK might get you killed'

One of the features of World of Warcraft: Midnight I'm the most excited for is Prey. In case you're unfamiliar, Prey is a system (that you have to sign up for) which will ambush you with a specific boss enemy you're hunting while you're out in the open world, eventually leading to a 1v1 when you take the bugger down.

It's an ingenious way to handle a spectre that's haunted MMOs for years: Open world difficulty. See, world quests, dailies, and the like are a core part of the modern MMO ecosystem—you've gotta do all your little tasks.
