Very doable on DNC/NIN
You will need :
Fan dance
EVA build (at least a decent ammount)
Lots of shihei
45 minutes
Mdef and Def down steps
Violent flourish for ichi cast
Fight it like any other mob, you shouldnt have trouble staying above 200 TP so should have plenty of FM for stun>ichi. Only thing to be on your toes about is be ready for occasional spikes of ACC and CRIT from him, always had TP for a cure if that hapened.
Good luck ;)
