If it's any consolation, Sakurai could easily "Luigify" Lucas, that is, give him some different attacks and such. If he did it with Mario of all people, this one should be easy.
And if you compare Ness64 to Melee Ness, he himself has already changed drastically...
Well, whatever happens, I'll be fine as long as he gets some good grab range. *sigh*
The one thing that killed Ness in Melee was, in my eyes, the weird mentality the team displayed while redesigning characters for balance.
Ness was nerfed with the mindset "give him some strengths, but also some weaknesses to make up for them".
Fox was redesigned like "give him weaknesses, but strengths to make up for them".
Hence, Fox was made light but was still a fast-faller, making him hard to kill off the top, along with a recovery with insane reach, which is predictable and has start-up time, so they added extra protection to it and gave him an alternate recovery that increases his unpredictability. Oh, and his attacks are weak except for those that are insanely powerful.
Ness on the other hand, has a godly throw. And a grab range that never allows him to use it.
Now who's the stronger one?
I actually sort of mained Ness in Melee. Despite his shortcomings, I was better with him than many others.
As long as he gets a good grab range along with a sped-up dair, it'll be alright.
And while they're at it, they can add to Lucas' individuality with some new special moves.
