If anyone want to hear my input on the matchups I'm pretty sure on, its...
Ness < Jigglypuff
Ness < DK
Ness = Falcon or Ness < Falcon
Ness = Link or Ness > Link [moreso the later]
Ness < Mario or Ness << Mario
Ness < Pikachu or Ness << Pikachu [moreso latter]
Ness < Fox
Mario > Link
Mario = Pikachu or Mario < Pikachu [later is more likely]
Mario = Fox or Mario < Fox [moreso the later]
Link < Pikachu or Link << Pikachu [more likely the latter]
Link = Jiggs [more or less, to me could swing either but barely, Jiggs problem is range and approach and Link takes care of that easily, and Link not even comboing does a good bit of damage, Fair is 20% if I recall, some others are 17% and such]
Link > Samus
Link = Falcon or Link < Falcon
Link < Fox or Link << Fox
Link = DK or Link < DK [depends on how well Link can deal with DK's range, if DK can easily get past its a game over for Link]
Just all my input, I didn't even look at the matchup chart.
EDIT: Will edit to PD
ness i think has the slowest horizontal air movement
General weakness, I agree
falcons recovery has the most variables to avoid ness besides pika
Falcon's recovery is a blimp with landing lag. Recovering low means Falcon will eat a dsmash or a dair. Recovering high means Falcon will get grabbed and thrown off [or bair, faired, or uair->combo depending on where he lands]. You have to be right next to the stage to be able to try tricking someone with Falcon's recovery. Falcon has a better shot than Ness if he can make it with the second jump, but if he has to UpB, he should never make it back.
Fox, Mario, even Kirby, EVEN YOSHI, have a better chance than Falcon.
there isnt >>> becasue there arent any characters that overpower another character in this game that much
There isn't >>> because it'd add too many variables. >> Means incredible overwhelm. > means disadvantage, = doesn't exactly mean = but it means close enough.
ness's combos are easily screwed up by platforms, platforms are on both hyrule and dream land
What? Platforms EXTEND Ness's combos. You get more output if you can uair from platform to platform. If you use combos just from muscle memory it'll screw up the combos, but if you can adjust you get much more damage output and a harder to DI combo.
Sometimes they'll screw with your combo, but most of the time they help a lot.
ness is fairly slow, light, surprisingly easy to combo, and has horrible reach not to mention very bad dash length
General weakness. Why I still think any advantage is Falcon's, just not >>.
yes falcon is easy to combo but after he gets 100% you have 2 options throw or dair to uair. but youll probably lose a life trying to get those set ups becasue of falcons speed and reach over ness
You also get bair, and attempts at fakeouts [nowhere near as good as Falcon's options but options nonetheless]. DJC uair too depending on what Falcon tries to do.
whens the last time youve played a high level game on console?
I could say the same to you.

But you can't assume broken DI for this stuff.
