When World of Warcraft Classic arrives in the summer, how will player-versus-player combat work? Just like it did when the original game launched, apparently. Blizzard has outlined a gradual introduction for PvP fights that will mimic the initial rollout. To start, there will be no kill tracking or reward system -- if you take down other players, it's mostly for the thrill of it. You'll have to wait for a second phase before an honor system and rank rewards kick in.
