How do you feel about heroic only bosses? Many people will not see them until several tiers later. Many people will feel the need to push their guild harder or find a more skilled one only to see this one fight you won't be able to otherwise. Granted a lot of people still won't see a lot of fights until later simply because they aren't good enough to clear normals. Then again blizzard introduced LFR for this very reason.
With the new direction blizzard has been going do you think there should still be heroic only bosses? Will a heroic only boss change your expectations for this upcoming tier?
