Luigi- Luigi can't approach us... at all so you're going to give him platforms so he has an extra way of getting to us? Umm, no, platforms are better for luigi than flat stages. Also, his projectile is a compliment to his approach, not a camping tool.
Pit- Pit spends a lot of time on the ledge, stage doesn't really matter. And actually I just got back from a tourny and played a fairly decent pit quite a bit. Honestly, I'd be much more worried on delfino than BF. And taken from the pit boards: CP Brinstar, delfino and Lylat
Toon Link- Tink does well on every stage we do and his projectiles while annoying aren't that bad really. If you don't feel comfortable on FD sure, go ahead and ban it, but, it's really player choice preference.
King DDD (chain grab too)- His projectile... waddles... really? I'll concede that seeing as how long FD is, that his CG is a little worse, but his "projectile" has no play when it comes to stage decision.
Snake- Marth beats snake here... we can juggle him forever and his grenades are distractions on this stage, just like every other one. BF/YI are FAR better stages for him than FD, we can't juggle him nearly as well there. *Hopes Shaya comes by to mention how marth ***** snake in general but even more so on SV/FD*
Mario- Again... his "projectile" is a compliment to his approach. And, he can't really approach you either, just like luigi. Flat is good.
Wolf- Do wolf players even shoot lasers at grounded opponents anymore? I would strike this because his dsmash will kill you relatively early, not because of the projectile.
Fox- You're going to end up running through his laser on every stage regardless. So banning FD because he can camp you... Besides, TKD always seems to take Marth to BF, so idk. I can see why you might ban/strike it, but I'd be more annoyed w/ something w/ a lower ceiling.
Falco- I'll concede this one to you, although, Marth definitely isn't shut down by any means here
Diddy Kong- I'd agree with this too
Link- Uhhh, sure, I guess? Bigger boundaries so it'll take longer to kill you while you can still gimp him
Zelda- Din's Fire isn't a projectile.... Also, ban frigate. Long platforms, and, if she trips you on one, she can drop through-> lightning kick. Much more common than on smalll platforms like on BF.
Olimar- Hell no, ban halberd. Stupid early as f**k usmash kill. Jab the pikmin off or ftilt them or w/e. You can actually ignore them being on you except the white ones.
Ness- *disregards*
Lucas- *disregards*
Also, how did you manage to put zelda and forget sheik? I'd agree to banning FD vs sheik. Needles are annoying and it's nice and big for her to run away from.
Other characters w/ projectiles you missed:
Lucario- While FD isn't bad for him, ban frigate, it's Lucario's playground
G&W- He is terrible on neutrals. Ban RC/Halberd
IC- I'd ban FD vs them
Peach- idk, maybe ban FD, although she does do excellently on delfino and can do fairly well on lylat too.
Pikachu- I can agree with FD. If you momentum cancel w/o having awesome DI you'll get thundered (only attack in the game that punishes you for doing something right, wtf?) and because of his QAC tricks he can camp you fairly well. Although, campachus seem to adore PS1 so I'd ban that one if you're worried about being projectile camped.
ROB- His projectiles are pretty telegraphed. I love FD vs him, he's so easy to juggle. Ban frigate vs him.
Samus- Maybe FD here. marth is just tall enough for her to missile cancel at any height and hit him. So she can easily apply some decent shield pressure here between missiles and zair.
Yoshi- Maybe RC? He can camp you really hard and really well on the dynamic parts of the stage although the normal static parts Marth ***** him on. Maybe Lylat too, idk.
ZSS- Ban PS1, by far her best stage.
Overall though, you should be able to PS almost all of these pretty consistently.
While I don't remember what all the taunts are, his counter is: Like I'd let you or something to that regard.
