Still, questing for hours on end can be a grind no matter how inventive the quests are, so I'm always relieved when Legion gives me an excuse to take a quick break. For now, I'm optimistic that as long as Blizzard can keep pace, Legion's endgame will be more accessible and satisfying than Warlords of Draenor ever was. Once I've had some time with the full endgame experience, I hope to have a better idea of whether or not Legion will become stale months down the road. World quests are essentially Diablo 3: Reaper of Souls' adventure mode stitched wholesale onto Warcraft, and turns the entirety of the Broken Isles into an endgame zone at 110-meaning I'm not stuck in the same area repeating the same quests over and over, but rather jumping around the Broken Isles day to day completing a variety of objectives for better loot drops.
The meat of Legion's endgame raids won't be available for a few weeks, but the world quest system is a smart revamp of daily quests that won't supplant the need for new updates down the road, but should keep Legion from feeling stale during the months in between.
