I can see Capcom's logic in keeping Dante, Lady and Trish in 4 as they were already facing some backlash for Nero but I feel including them ended up hurting the story more than it helped. Not that the DMC franchise is known for great storytelling but DMC 4's didn't even seem to be trying and I think one of the issues is the need to include the previous three protagonists.
Dante basically just steals Nero's thunder as the protagonist. and thus invites comparisons to Dante they do not need. Lady does nothing of note other than telling Dante about the order and is just there for fanservice (in every sense of the word). Trish's inclusion is handled the worst. She does nothing to stop the Order's plot, in fact she furthers them by giving them Force Edge. Worse, Sanctus deduces her identity before she even does anything of use. We don't even get a token scene of her protecting citizens during Sanctus' attack.
Instead of relying on the old characters, Capcom should have let Nero stand on his own, at least for his debut game. Maybe after this you could bring in Dante and the others and have them meet for a possible DMC 5. But for DMC 4, there presence did not help.
