Good and yes, but I'll go into some detail on a few things.
This is basically directly in line with what I was saying, in that I've yet to hear people talk about the character in a way that they understand top level Luigi at all. Understandable though, and no offense if that sounds mean.
What I mean is that people have to go through great lengths to try and get around weaknesses Luigi has. Other characters can WD OOS after a shield hit, but it's usually not to stop a butt load of momentum, it's to get a bit closer for the punish. Luigi's shield pushback is a weakness and to address it, people already try things like WDing out of it to stop the momentum. That's not irrelevant because Luigi misses out on a lot of "normal" punishes the cast can get OOS because he slides back so far.
What I'll say here is kind of obvious, but anyway.
People shouldn't be trying things with Luigi if those things don't work, (just like any character wouldn't).
Whether it's trying to force a punish on something with a WD OOS, or even just considering missing those 'normal' punishes and instead getting 'not normal' punishes as something negative about the character. He escapes things differently (shield sliding), gets different punishes (WD speed), but there's just as many ways of punishing him for shielding things, and just as many ways for him to punish others for shielding things. It's just different, no difference in goodness/badness.
If anything, I find it trickier to navigate around simple things like Fox lasers or basic projectiles, not safely, that's easy, but in a standardized/methodical way. Since they force the WD if you shield (stops momentum in its tracks if anything touches a shield mid-slide) which has a lot of excess distance to it, so doesn't allow safe approach by conventional means if leaving the shield at a greater distance than 'normal' characters.
^ That's where I see your point mostly applied as a negative.
Most of the sliding/shield game completely counter-acts itself (along with Shield-Pressure > Punishes in general) with the way he doesn't really have to be in those situations nearly as much as others, as his speed (OOS too) allows him to bait with Shield/whatever from further away than 'normal' anyway.
It's irrelevant in any advantage/disadvantageous way. Luigi has options OOS as much as anyone from Peach to Marth, all 3 of their OOS options (from all distances) aren't parallel at all. This is where the misunderstanding comes in. One of them is considered to have none (or little) because they're unconventional compared to the rest of the cast, and literally not developed in the public knowledge base, no matter how much commonly it's accepted as 'known'.
If the majority of the cast functioned like Luigi from Day 1 Melee, then Falcon-style would be the out-cast of Melee, and underdeveloped to due obscurity. Guaranteed.
Luigi's airspeed is a blatant problem and holds back the character in quite a few areas. He doesn't need to move as freely as Jiggs or Wario, but a little somethin somethin would be good.
Everyone has their quirks. Somebody has to be the most mobile, someone the fastest, some one the slowest, someone the smallest, Luigi gets his extreme. It's good too, cause his aerial game is already good for not being able to move. lol
People need to play Luigi more grounded and consider walking more. I dunno about your pivot ideas, but yes people need to not be caught too much in movement as Luigi. Poking with Luigi is muy hard: if you WD in and try Ftilt, your momentum is likely to carry you into the person for an easy shield grab or punish. Maybe if your spacing is good, you can do a tiny WD forward and then Ftilt. I really dunno about DD Pivot tilts or blah blah. Sounds like a good idea for being in place, but not for actually approaching the other character. Like those suggestions sound a lot better for walling or stuffing the opponents approach than being used as an actual approach or threat. If Luigi is DDing in place, then I basically am glad that he's not trying to close the gap. I don't want Luigi in my face, he can sit out there on FD center and DD all he wants. If he is gaining ground, then move forward and shield, or walk forward if your character has great poking. Now the bar has been raised ya know? Like to get inside of people's range quicker, Luigi basically uses movement boosts. Either from WD or from the less common Down B. Walking and even running at someone with Luigi can give you more options for tilts and for not being in WD lag, but it's also a slower process and he's still worried about better range while walking up close. IF you believe that Luigi, out of a DD or walk, can be precise enough to reliably try and get past Marth Sheik etc, then I would at that point advocate playing a character with better options and better movement out of a DD because they could do it more capably than Luigi could. The kind of gameplay skill that would take would be massive, and may not even be enough to get past a defensive character/strat with range.
Yes.
I'd really rather not intellectualize this stuff, or go into character specifics (this is the longest endless tunnel EVER lol) but whatever. One more time. haha
If you WD > Walk backward (for literally even a single Frame) in PM, your momentum is halted entirely.
Nobody should be getting shield-grabbed as Luigi anymore than any other character, if so, that's simply poor play. Hence the rest of your post, and how he shuldn't be WDing all over and over-extending everything. That's like saying other character have difficulty getting shield grabbed because they over-extend SH Aerials. It's essentially irrelevant in actual proper play into you get into variables like intentionally screwing up an opponents spacing with your own maneuvering (this could be argued 'against' Luigi, since the most common way of doing this is DD Shield > OOS option, which Luigi may lack since it's such a close-quarters thing that usually implies 'barely' punishable things from the opponent in the first place).
Spacing stuff is harder with 10 frames of going infinite mph, if the player isn't using this for what it is, and tries forcing stuff that way all day. It's 10 frames of super speed and should be treated that way, AKA should be treated as something that will over-extend if used improperly.
WD Forward > Dash Back > Pivot Ftilt is something I've only known 2 Melee players to actually apply to Luigi's game, and it's a core part of his game that the common public seems to simply avoid/ignore. Approaching with it is as fine as WD Ftilts, maybe a couple frames slower, but essential to his game. It's just more reason I consider Melee Luigi to be the most difficult (mainly due to obscurity/uniqueness that translates to being foreign technical/mental concepts to the game) character to play in any Smash game to date. Many others consider this as well when they bother learning the character to any decent extent beyond BnB stuff.
He has a great DD that most Luigi mains (and players) seem to avoid, oddly, but understandably (Dat WD!), and neglect, as well as amazing Pivoting tools. His neutral game is actually as strong as it gets in the Melee cast, and it's even better in PM. Unless this is understood, then the Luigi-insight is lacking. Again, no offense, this just is, but I can't really explain this any non-pompous way so I understand if you 'judge' this as being rude and ignorant or something. I can wait, it's been a long wait already.
Down-B sucks. lol
It's best use (aside from recovery) is slightly altering his fall timing to hopefully avoid/counter-hit an attempted swipe at him when he's caught in the air. Rarely is it the best option anywhere else, from tech-chasing to whatever.
Marth-style movement involves a mix of WD's and DD's, etc. Luigi's is the same. The combination of the 2 implies Luigi (or Marth) should really never be DDing in place, or approaching at a frame-disadvantage. This, again, goes back to people not playing Luigi in a way that makes him work. Nothing more.
He can get 'past' (not that getting 'past' a character is something Luigi should be trying to do anymore than anyone else...) Marth/Sheik isn't a problem. Don't get hit, #1 priority. Luigi's troubles come from getting, hitting people is easy. Especially with the things you WANT to hit them with.
People are missing things with him, but not to the point that he shoots up as a strong character.
I like this sentence, and it kind of explains the rest.
People are missing something, they know they're missing something, yet... this is implying that people know that what they're missing has certain qualities. They're missing it, so how do they know the qualities of what they're missing?
This is so contradictory, and so common. Not just for Luigi.
It's awesome, and I love people for it. <3
Me included.
He's a fine character once he gets inside and goes to work. The process of getting there is not fun, and there are MU's that basically hinge on baiting them to swing/swat first as a mistake and then you punish. Which is hard to accomplish the higher you go up, as the person will be less willing to "just" throw out the attack if they can wait a bit longer.
I've never had this problem, and if anything, I've found him to be more capable of 'getting in' at a top level than most. He's too fast and has too much range for this ever to be an issue, unless it's simply not top level play that's being referred to, or applied poorly in a non-optimal way, as you've mentioned, is the case for Luigi.
The 'case', as is constantly argued, is that it's not enough. I simply know it to be enough (others do to) so it's really just a waiting game.
I'll simply see if it comes before he's over-buffed. That's all. In the meantime, these discussions have funny circles.
/end the rant for the billionth time.
