I think iam kind of at a loss here. I find it hard to believe that he actually thinks they were 'hard'.
By the middle/end of the expansion I remember steamrolling them like any other heroic dungeon. At the beginning of the expansion they were a little difficult, required some CC but thats about it.
By the middle of the expansion people were so geared that you could just pull 3-4 groups like a normal dungeon.
I fail to ever see this point that he claims where heroics dungeons were really THAT hard to accomplish. Maybe its just me though.....
