I was already thinking about taking Attumen on with my paladin and 4 shaman, seeing as my paladin takes such trivial damage in that fight. Now I don't know that it would be so extraordinary.

Keep in mind though, I don't think this change was designed to help people see the content and get gear for levelling. Progression raids won't see a whole lot of improvement because of the effects of the downranking, heroism/bloodlust, leatherworking drum, and shadow priest nerfs. From that perspective, this change may have been designed more to ensure that guilds who are farming Sunwell don't start wiping on content they've been farming because of longevity issues.
