You act like those things are mutually exclusive. They're not.
Stage knowledge is a PART of your fundamentals and match up knowledge...unless you're one of those players that seriously strikes to Smashville every time, no matter what you're employing at least
a little bit of stage knowledge during the striking phase, and counter-picking phase. You could be a relatively strong player and still make a bad stage pick. Like, IDK, letting Sonic take you to FD.
Learning the stages does NOT take a significant amount of time.
There are resources right here that explain things in more detail, and a few minutes in the lab can help you familiarize yourself with a stage's features. You can also try wackier stages out in friendlies too, if the other player is okay with it!
Knowing the stages in and out and how they particularily interact in all matchups DOES take a lot of time. Seeing people group Miiverse with BF and say that we don't need both shows how ignorant some people can be. It goes deeper than "don't let Sonic go on FD" or "SV is Sheik's best stage". And working the fundamentals takes even more time and practice, really.
PS : I do love playing on strange stages in friendlies but that's not what this thread is about.
On FLSS: I don't really see how that it can be considered more complicated than the current system, which is already somewhat arbitrary and a holdover from the Melee days. And yeah it's unfamiliar and a lot of players are probably going to stick to what they're comfortable with, but they would do that regardless of the stage striking format. That doesn't mean we shouldn't experiment with the rules. (BTW, FLSS doesn't have to be for a large number of stages, it can be scaled back for smaller stage lists...)
Well the majority of the FLSS advocates are for a stagelist that is 9 stages or higher so that's why I make the implication.
But of course if you want to FLSS on a smaller list (5 or 7) then everything is fine since it's virtually what's already happening with the S/CP system. People mainly pick their stage from the starter list and barely go on CPs, so statistically it's the same as doing a 5/7 stages FLSS.
Really now? In the OP I have already put up an example which has disproven this via game1 castle siege.
And how many sets in the whole tournament started on CS ? Out of something like 2 thousands of sets, how many went to something that wasn't considered a starter ? Is it worth it to complicate the ruleset of an international tournament just to get statistically insignifiant changes ?
I went to EVO myself, and struck smashville against every Shiek I played against, and the games didn't necessarily go to BF or FD.
Or unless you're one of those guys who believe only the opinions of those who placed top 8 matter.
First things first : It's not about the opinion of people (moreover top players often have a very biased view of the game so their opinion is rarely valuable), it's about statistical sampling. Sets that happen in the top 32 of EVO show more of how the game is supposed to be played compared to the rest of the bracket and thus are more reliable when it comes to discussions about the meta, be it in character choice and stage choice. You striked SV against all the Sheiks you encountered ? Good, how far did that bring you ? How many Sheiks did you beat ?
See, everyone was going on about how DK was broken with customs, but we didn't see any DK in the top 32, instead we got a GW that didn't use any customs and just relied on his very good basic skills.
I said it above and I'll say it above, I love all kind of stages and I have fun with them on friendlies, but what we're talking about here is their tournament viability and as much as I love DK64 I wouldn't want to see it tournament legal. You have to draw a line between what you like as a person and what is good for the competitive health of the game.
