@DarkCainX Then you're misperceiving what "average" is; I assure you, if you were clearing 4.0 raids steadily, your group was above average.- Watcher (@WatcherDev) May 12, 2014
What Watcher is pointing out here is that for many of us, our group of peers is the game. We only see the game we play. Any assumptions we make about the game (such as, the difficulty of the raids, the quality of our fellow players) can be hampered by the assumption that what our group experiences is what all groups experience. The tweet that Watcher responded to argued that the Cataclysm launch raids weren't overtuned because his peer group, which he considered 'below average', was clearing them. Watcher's response points out that it can be difficult to define what the average is, much less whether or not you're there.
