Two weeks ago, we published The OverAchiever: Why Icecrown was less fun than Sunwell. It's definitely become one of the more controversial OA topics I've written about and attracted a lot of discussion, neither of which I had really anticipated. Some people agreed with me, some didn't -- but either way, the comment thread is a very interesting read.
While I hadn't been intending to revisit the topic so soon, I lost internet access after Hurricane Irene strolled through my area and had an extra week to mull over the points people had raised. The conclusion (perhaps erroneous) I've reached is that, if anything, the issue is more complicated than we all guessed, as the normal/achievement/heroic split may also point to a deeper systemic problem with the 10-man and 25-man model, too.
