You know I could pretty much take your exact post and turn it around, with arguments for why AOE damage is important to; get shorter phases with high damage, get rid of certain mechanics, bring less healers and thus more DPS, let good single target classes focus solely on single target etc.
I don't want to go through each boss, I'm sure people who raid heroic content is well aware of the massive amount of AOE in SoO. And why do we even discuss this, did you miss the point about warriors being the 4th best single target class, only 4% behind the best performing class (warlocks)?
