I already had Loremaster, but I'm going through the remade zones to get the new quest achievements. After about ten hours worth of play time I'm almost done Eastern Kingdoms. The new quest chains are brilliant, it's amazing how streamline the zones are. No more hidden NPCs and seven spots in a zone you can pick up quests. There is certainly some kind of downside to that, but there are still achievements to encourage out-of-the-box exploration and it will definitely make questing faster for old hands and more intuitive and enjoyable and modern to new players. Cata is really bringing the game up to a fresh standard in a lot of ways, it almost feels like a new game.
