Like I said, it's an epic post, and we won't reprint the whole thing here. This, however, is the key takeaway:
All that being said, though, is Blizzard really satisfied with its dungeon designs and their current level of difficulty? Hard heroics are indeed hard, but the updated PTR patch notes for 4.0.6 (which went live just yesterday at almost the exact same time Ghostcrawler was discussing heroics) indicate that a series of nerfs is coming our way. That will no doubt lead to player rejoicing, but remember -- heroics are naturally getting easier as people get more familiar with them and players continue to compile better gear, which makes completion even easier still.
