By now, you probably know the drill: a new World of Warcraft expansion comes out, and the level cap soars to new heights. In the past couple expansions, though, focus has shifted from traditional leveling to alternative forms of advancement like Keeps, Order Halls, and Artifact Weapons. Zones have also become non-linear. I asked Blizzard if regular leveling will ever go away entirely.
