I touched on this a few pages ago. My favorite job combo for myself was actually WHM/PLD with all defensive gear, a Hammer and shield, and 5 MNK/PLD's at my back trolling bones.
I miss those old bones parties :/
there is just something satisfying about watching 5 MNK/PLD's wail on a Bone while you are tanking it as a White Mage and it can't even attack because of your job traits and defensive skills.
