sorry i was just rambling...tired, but nah actually
i only wanted the answer to this question:
"but if you don't hold shield and powershield do you still have shield drop lag of 14 frames (with marth)? "
i seem to remember testing it at one point but i can't remember the result..i have barely played melee in teh last two weeks..i think i played less than 10 hrs....i'm forgetting how to play this game
and mahone keeps saying he's retiring..so there's no one to play
edit: i'll add in one example from you that I considered to be instrumental but that i haven't seen marth's implement in marth vs sheik
in marth vs sheik one of the fundamental problems is that sheik punishes marth for dashdancing more than most characters. For that reason, wavedashing during your dashdance tends to give you more options and leave you safer....in particular i think marth's should try wd backwards after aerials sometimes. character's like jiggs already do this all the time..but for marth this helps a lot when sheik is boxed out at the ledge so that you can get stronger punishes and not relinquish space as easily while still maintaining mobility...
also i spent two hours testing sheiks options with marth boxed out at the ledge and in particular sheik's ability to dash attack marth in the start up of a jump on reaction and it is quite frankly purely impossible at a decent range...marths continue to say this but it just their fear talking (which is understandable as i thought the same as them when i ate 9-10 dash attacks in my first few sets in tourney) but sh when the sheik is out of threat range is not that bad and is a solid mixup for dtilt and walking forward...
in particular if sheiks are reactively dash attacking in response to your movement forward you can punish them off of a sh quite heavily...and if they don't dash attack or move in reactively then you can start walking forward and dtilting to get more space...without being willing to jump forward the sheik can react to movement since you don't have room to dashdance at the edge and just dash attack (or grab) every time you try to come in.
also, even if the sheik is not going for reactive dash attacks, which sh definitely clears unless the sheik was too close and you hadn't made her scared to close in on you, you can still take space with the aerial, you just have to make sure that you give the space back up most of tte time since most sheiks tend to try to punish that landing lag, but then if you guess right (as to how and whether they come in) , you have an option to punish their commitment.
moreover the marth boards basically told me that CC and shield means sh forward isn't safe, and for someone like me who has been playing 90% aerial for most of the last year since i couldn't fully dashdance..I agreed with their assessment that dtilt was amazing but i had a very difficult time believing marth can't take space safely with aerials..even against sheik i think it is a solid mixup..(i think this now after testing marth's options at the ledge, yesterday i didn't think that fair was good and had decided it was bad and told PP in PM that i wasn't convinced [though for different reasons than the marth boards chose...more because i thought they could wd back on reaction]..but with testing i realized that being able to make them play reactively is in itself pretty good and opens other options..moreover i realized i had more options off my sh than i thought i did against sheik..
but then i didn't feel like arguing with the boards...because i thought they were probably thinking about sh forward from a closer spacing than what i had intended because neither I or anyone else had specified what spacing i was at relative to the sheik..
but my first statement, that m2k played massively aerial based vs amsah and most of the other sheik matches online was true enough...so i knew something must be good about it...also, i had already spent 3 weeks studying the marth matchup on the boards that just says stay on the ground, play grounded, CC a lot and dash dance for your grab, and playing from that perspective before....but it definitely didn't seem to work for me
not saying it can't work, but it seems to struggle to get kills a lot more...other than that i don't fault it in particular, it may even be better..
but when they started saying that aerials are a bad way of taking space in general....i just started second guessing everything i had learned in the last year about marth. I kept thinking, sure i can go around 45-55 while using aerials to take space against a fox that places 30something in nationals...but maybe at the pro levels it's not valid.
but there is always variation in how people play matchups...mango is so damn aggressive playing marth vs fox with his aerials i don't even know how he manages to throw out so many aerials and still maintain any semblance of spacing..but i feel like the current marth metagame is massively slanted towards a ground game...and to be blunt PP..it's all m2k and your fault...dashdancing seems so effective that everyone stays on the ground constantly now. And for a second example in another thread, another marth was talking about marth vs luigi and even though i again agreed that staying on the ground and just dtilting a lot was good...they stuffed someone for suggesting getting on the platforms because luigi will just get under you and you'll get punished..i'm sorry but CC, shielding, and getting under marth are not nearly enough to invalidate marth's air game or his platform game ( at least vs the slower characters...against faster characters i probably wouldn't risk getting on platforms unless i'm boxed out)..but the reason i know this is because when i first played vs redd's ICs i had no clue how to play the matchup, so I was forced to platform camp to avoid grabs that I was afraid of...not an optimal strategy maybe, but i had learned quite a few mixups from platforms from those....and luigi's second rate range is nowhere near enough to invalidate those options.
but after thinking about these discussions i realized, it's not their fault, or my fault, or anyone's fault really..people on smashboards don't want to enumerate all the possible spacings and options in a matchup.
WE ARE HERE TO SOCIALIZE AND RELAX!!!!
instead they tend to speak in generalities in the matchup when in reality a 3 millimeter difference in spacing along with the difference in whether the opponent is currently attempting to react to your motion or deciding to retreat/approach completely change the validity of options. Because of this and a recent revelation that I was utilizing a lot of options against sheik that are great against spacies and horrible against sheik made me realize that i needed to write out the options for some matchups I realized that smashboards tends to just be people giving general information about matchups without many situations elaborated upon.
so if i want to get better, i need to list out the situations and test them. so i spent 3 hrs enumerating various positions and options in marth vs fox from neutral to determine which options i liked out of my various punish options (on a side note just on ground positions when not boxed out at the ledge, between the options they have and whether they are reacting or in neutral or dashdancing in various directions, along with the variation between close and wide spacings and whether you are in lag, there are probably over a 100 variations, but in reality as you realize what are optimal punishes, you realize that most of the options just condense down to maybe 15 or so situations)
...one notable thing, reactively taking space with sh is significantly better than just sh forward and letting them react. I think the most useful thing i learned in those 3 hrs is that if you don't dashdance constantly and treat dash dance as neutral you have significantly better options for punishing and taking space as you won't be randomly dashing backwards at times when you wished you weren't. that and SH in place seems pretty bad except as a bait or when they are boxed out or you are boxed out at the ledge...movement is nice with your aerials normally.
i still think dashdancing is good, but spammed 99.9999% of the match like most players do is definitely very limiting..
for the tl;dr crowd,
just remember what pp said about wavedash being nice in marth vs sheik and especially consider it after some aerials
