I never really gave a synopsis. I said that Lucario wasn't as good as he is commonly thought to be and that I think he loses to Meta Knight in a 6/4 or 65/35 sort of way. Note that Lucario losing to Meta Knight isn't the same as X Meta Knight player beating Y Lucario player. There's more to this than who is beating who. I just think Meta Knight's tools in the match-up are superior, but it isn't like Lucario would be unique in this regard.
I actually do not think anything about the Pikachu/Falco match-up. I play some Pikachu and to me, it has always seemed that a low-percent chaingrab doesn't make a match-up. My (uneducated) opinion for a while was that Falco isn't super-easy to grab anyway. However, I saw a post by DEHF somewhere that directly addressed this very concern; Pikachu when well-played can often get the grab at a low percent and get 90% free per game. (I recognize that this is not really relevant but DEHF says Pikachu is unwinnable in this post, if anyone is interested I can try to find it). In this case because my hypothesis (which directly affected this ratio IMO) was directly addressed by someone who was able to answer my question, I accept that the match-up is pretty bad.
Keep in mind that when I said Pikachu hard-countered Falco it wasn't a challenge, it was more of a fact regurgitation in an attempt to reach a separate conclusion (that although Marth and Falco are similar in that they are countered, Falco makes out better because Pikachu is rarer).
This whole mess was started by someone who was attempting to draw conclusions from my post that I didn't really make. Instead of saying "that would be true, but Marth doesn't really lose that badly to MK anymore, it's more because of X" they say "lmao ur an idiot marth doesn't lose to mk."
Do you see why I'm a surprised?
Sure. Let's so with this. It's not really an argument, but ok.
As for lucario being a lesser character then intented, outside of the metaknight statement, what are the reasons? He loses to metaknight, in terms of numbers 6:4. I feel his hardest MU is Marth and D3, for these intended reasons.
Metaknight does have better tools then lucario, has more range, and is faster overall. AS plays a big prat in this MU unlike other characters however, because metaknight has transcendent priority. Because of this, Metaknight has to use a defensive option in order to dodge or protect himself from the AS. This results into further reads for the lucario do against the MK in the MU. If he reads a fair, he can challenge with AS, and the same goes for his other moves as well. In the air, he is superior, but you have to do it proprely. Dair camping does not work on Lucario, and on terms of being juggled Lucario's dair out ranges MK's Uair.
Now as for Marth, he does everything MK does in this MU, but to a better extent. Marth is not superior on the ground on terms of MK, but he has the tools needed to put lucario in a state where he has to run away a lot. Also, unlike MK, Marth's forward pressure shuts down Lucario. His fair out ranges anything he can do to apply pressure, and unlike MK, Marth can actually just swing at AS instead of using a dodging option to block the AS. His fair will cut the AS until Lucario is around 135%. He can also juggle him very soundly since his air moveset out ranges all of Lucarios. Our only real option is bair, since it out ranges his fair due to our hurtbox being pulled back on the move, but it is too slow to use as a constant option.
People take for granted as to why D3 wins the MU hands down, but it is for edge guarding. Unlike Marth and MK, a single option (grab) can get lucario off of any stage, and Lucario recovering against D3's air options are very poor.
Other then that, what else makes Lucario a bad character? There are only about 4-5 characters in the game who shut down his approach options. He is not the fastest, but he has enough speed and frame data to get what he needs to get done, done. His worse is a 6:4, and maybe for Marth is a 65:35, but other then that he is 100% viable and usable. Where he is on the tier list I feel is perfect for him.
