I know. I've S ranked all other missions but 5 on DMD with Nero. But the thing is... Everything gets so repetetive... It does with Dante too but with Nero it does that 20x faster. Dante has a arsenal made for him to switch up and change fast to do a gigantic sum of multicombos.
Always have charge shot 3 up and go. Use buster/snatch on Mephisto/Faust. Don't use snatch on Sanctus, walk under him and do a high roller so he does not fly away. I even knew how to do max act through all of the aerial combos and a few of the ground ones. But all that is gone now... Because I don't like playing as him anymore.
