All this talk of no /dnc in merit parties is nonsense tbh. With the right party setups /dnc can be quite useful in a merit party.
A couple of my favourite setups i've had with myself on mnk/dnc are; drg x3, brd, war and mnk/dnc in Mount Zhayolm on trolls was not only fun, but good exp. Of course you can swap brd for cor and just have any job /war replace the war for the initial voke. Another good setup i've had was mnk/dnc, brd x2 with a combination of 3 war or mnks with nin sub jobs at the Greater Colibri camps. One brd comes /nin for pulling while the other comes /whm to help the mnk cure, yes I main healed with this setup. The fact the 4/6 of the party is /nin means there isn't much need for curing, especially since the mobs die so quickly. Again it's not only good for exp, but it's also fun.
