The Fireball is better in this game in my opinion. It's not the best projectile out there, but it helps Luigi approach and space more. I dunno why, but I feel as though it improved since Brawl.
The Green Missile is bad outside of his customs. The distance is limited if you don't charge it, I wouldn't trust it in KOing opponents, and it has very low priority (even Sheik's Needles beat it out). This was a move that should have been buffed.
The Luigi Cyclone is much better in this game. While it is weaker in terms of damage and it is harder to recover (possibly due to the 3DS), all of the hits connect better and it's an amazing combo starter. If I can't use a down throw, I use the Luigi Cyclone to begin my juggles and combos. That and using the Luigi Cyclone to KO opponents at the top of the screen is very fun.
The Super Jump Punch is weaker in terms of power and they oddly nerfed his recovery with it. It's still a powerful move with high risk and high rewards, but I don't find myself using it often.
Overall, I think that Luigi's specials are good in this game. The Fireball and Luigi Cyclone are better, the Super Jump Punch was nerfed but it is still a good move to KO with, and the Green Missile is still pretty "meh."
I should've posted something entirely different. My problem was basically realizing how overbalanced Luigi was compared to rest of the cast. Like how Dr. Mario's upb kills about the percentage that our fsmash kills (115% I think vs mario), but has exponentially more range, and I feel it's less punishable as well, also I think it has more range than Luigi's custom. I'm just upset with a lot decisions they made with him. I feel like the chance for a misfire should increase with each level, even if it was a misfire every time it still loses to fireballs, and I think people can trade regular hits with it (not sure). I just feel like other characters like Yoshi and Greninja (to name a few) can have their cake and eat it too, while Luigi has to suffer because under uncommon conditions he can be god like.
If the chance for misfire increased as you charged, if the invincibility of up b (which is useless for it to have!) was given to forward smash, and up b was properly balanced! Meaning it would either have zero range or be extremely punishable, it can still have low range (even though it makes hard to punish because Luigi's isn't that quick), but your opponent shouldn't be able whiff a dash attack, then whiff a smash attack, and still have enough time to hit you. Then I think Luigi would be one of the best in the game, but I feel he's not nearly as good as he should be because he was balanced under the impression that he would always be hitting misfires and sweet spotting upb's.
AND DOES EVERY CHARACTER MOONWALK AFTER THEY GET HIT, or is that a Luigi thing because I don't think Luigi can punish Flare Blitz because of how far back he slides.
I think Green Missile is pretty underrated its the perfect situational tool like after link/tink or someone whiffs a down air. If you can surprise someone with it it can also throw them off. Also for some reason I feel like you have more of a chance of misfiring the less you use it, but thats probably not true.
I don't think it's underated at all. It's slow and punishable, so it kinda sucks, but it's god like when you can take out the risk, which is what I believe you were saying. Like when you're punishing. This is why I've been asking for frame data and misfire set-ups (any kind of safe missile). It's godlike because you have nothing to lose (when it's not punishable) and if you hit a misfire you can kill them below 100.
