I have run every heroic in blues, including ICC 5 mans. I'm really disappointed at the lack of challenge from the 5 man content in the game. In BC you had heroics for the people who really wanted an extra challenge until blizz thought it was a great idea to turn heroics into normals and basically remove that extra lair of challenge. I have literally never had to run any 5 man on normal in LK since I hit 80, that doesn't seem right to me. The fact is there is no amount of challenge that they can add to 5 man content that would keep me out and not keep out 90% of the player base as well, so let them do whatever they want .. people will 5 box it as sure as the sun will rise tomorrow. Go watch some of the old movies of scarlett 5 boxing BC heroics when they were actually hard, that guy was as efficient as most normal groups I've seen.

Why you think people should quit because they have a complaint about difficulty is beyond me, theres still a lot of areas of this game I enjoy that doesn't mean I'm not going to advocate improvements I think I would enjoy.
