The other two posters are right on about Morgana's. From what I can tell, places like limbus, dynamis, any exp mob(I like Aura Statues), most low to mid level NM's, and even a few HNM's. Where it starts to get rough is on mobs that even Blm's seem to have a rough time. Like Gods, High tier HNM's. definately a good piece of gear, though gearing for Macc in other spots may become a requirement depending on what your fighting. Nothing a balrahn's ring and omega ring cant fix, or any of the other slots that can equip Macc.
