Is this truly wrong?

Yes, thats why I suggest SSS to figure out wether its someones rotation thats a problem or if its mechanics. (afaik SSS is also calculated without party buffs and the like in mind - its basically really telling you wether or not you know the "mechanics" or "rotation" of a class well enough and if you're geared enough to pull the DPS required)

Most SSS dummies are overtuned. Remember NIN SSS for Delta? Or MNK this patch? 5500dps to kill that dummy. (Sam was 5660 too!) It was nearly impossible to beat with 4.1's BiS even with pots and food, but plenty of low ilvl monks and sams went and cleared o8s regardless with much less than 5500dps for Clown on wk1. Alexander's SSS was also notoriously bad.

My point is without actually watching someone, it's difficult to pinpoint exactly where the problem is, even with logs.

Edit - IMO SSS should be at least 5 minutes, preferably 9 minutes long. You shouldnt need to alter a proper raid rotation to fit more buffs in a 3 minute dummy fight, when there are no 3 minute fights. At the least it'd be a more accurate dummy.
