As mentioned before, I'd like to see the amount of inputs required to get full vertical lift off of the Weegee-nado reduced. I don't know if the amount has been upped from Brawl, but I feel like I have to mash so hard to make it even remotely usable for recovery. On the ground it's easy as pie, but it feels like the aerial version takes 2-3x as many B spams.
Without it, Luigi's recovery is super predictable. Even with it, it's pretty predictable when you're investing your entire being into mashing B.
Also I can't tell if Mario's rate of fire (geddit) on his neutral B has been upped since Melee/Brawl (since I didn't play him often), but if Luigi's fireball speed matched Mario's, I'd be a happy camper (quite literally).

Honestly, the mash isn't that hard. Personally, it's like a reminder to me of "Hey, you F'd up, you shouldn't be off stage." since as a Luigi player, you DON'T want to be offstage...or better put...you don't want to get hit period lol.
Dude, trust me, buffing fireball speed would be ******** how OP it'd be. You wanna know why? Right now, if you throw out a fireball with correct spacing, you have an almost guaranteed follow up on most matchups, provided your execution and reaction time to the reaction of the opponent is on point. On taller characters (Bowser, Ganondorf, DDD, DK) an appropriately spaced Wavelanded Fireball hitconfirm leads into a GUARANTEED Shoruken, USmash, DSmash, or Grab. The fireball is also really good for edgeguard if used intelligently. if you get Marth from the distance with one while he's offstage, he's dead. Some matchups like Link allow for offstage setups for Dair follow ups.
In principle, the fireball is great tool to use IF you have the spacing to do it. You can't abuse it, but it can be a viable tool to fight campy players til you can break their CC.
However, let's think about what Luigi could do if he had the fireball speed of Mairo.
Due to Luigi's WD, majority of Luigi neutral would be this:
Fireball->WD->Something
I can tell you for majority of the matchups, the beginning 40% would be Fireball->WD->Grab, CG tech chase, 40%-75% Fireball->WD(or dash)->Dair, finally at 75% or more, Fireball->WD->Shoruken. It'l basically be a more braindead Falco/Mario. The fireball edgeguard would be ridiculous since you already can rack up a good 14% each time if you play your cards right when edgeguarding.
Hell, honestly Mario's current fireball speed is a little too quick, I'd speculate it's going to get slowed down just be of how dumb the neutral has become for Mario...at least Falco can't afford to take a hit.
And if you're looking for tools to get in, OnFullTilt made a pretty awesome guide, though as a far as application goes Luigi's "textbook" is still in its extremely early phases. For the most part, you need to wiff punish approachers and fireball til CC limit campers (see link below, thanks Cubelarooso). The only times you go "in" is to chase your opponent retreating or place extremely well spaced shield pressure (great for abusing lower level player's lack of OoS option knowledge). At least, that's my two cents. Take it for what you will.
