You couldn't reasonably turn Auchindoun into a single dungeon without it feeling like a massive clusterfuck because you'd move from plundering Ethereals, to crazy Draenei, to Arakkoa, to Shadow council.
These are four groups that have absolutely nothing to do with each other, it makes no sense to put them into one large dungeon.
They weren't.
If you ran Maraudon, you didn't call it after you killed Lord Vyletongue because he's the Final boss of a wing, you went on and killed the Princess as well, maybe even went into the other wing a bit if you wanted to all quests within a single run.
It's not like if you're running Slave pens, you're somehow obliged to do Steamvault after as well, because they are clearly not connected to each other.
