The only nerf I want for her is for Luma to be disabled longer after Rosalina is hit or grabbed. It is too easy for Rosalina to get free hits in when she should be getting hit.
I have gotten some fraudulent wins that way, and I honestly wouldn't mind if they did increase that time if they left everything else untouched. Otherwise, I don't feel like she's a character that deserves nerfs. Though a great character, her huge hitbox and extremely light weight balance out some of her more powerful qualities. Along with a lack of killing movies, I think she's relatively fair, though customs is another story. I don't even think customless Rosalina is that good.
I think I'd heavily reduce the lag on her luma shot return and not let luma act while returning to her unless she calls him manually. I don't really mind if it can act out of light hitstun like jabs or whatever, gotta give the mashers something, but not being able to chase her into the air because luma's return path will intercept you is at least the 3rd most obnoxious thing ever.
