The main difference between Mario/Luigi and Ness/Lucas is: Luigi is one of the most recognizable characters of Nintendo. He can't simply be dropped (although I would be fine with a more unique moveset). Lucas, on the other hand, is from Earthbound, which definitely isn't as well-known. I understand that Ness and Lucas aren't complete clones (like Lucina), but for a series that isn't well-known and only has two reps, they could stand to be more diverse (like Marth and Ike from Brawl).

PS I agree with you about Lucina. I was disappointed that she was basically a carbon copy of Marth. She will probably miss out on SSB5 unless she gets a moveset update or fans absolutely love her playing style.
