Still illogical. Does Falco play rushdown? With that mobility? I hope not. Does Falco try for more ground-focused kills? Nope, he doesn't have much to setup a ground kill and Side Smash doesn't true combo from anything while his Up Smash is purely for damage and anti-airing. Does Fox edgeguard like Falco? Nope, Fox lacks high, but not too high knockback on his lingering aerials to gimp, his double jump doesn't go as high as his Falco's, and while Fire Fox travels far, Fox will be in a much more severe disadvantage if he's left that low where any hit could gimp him not to mention it's heavily telegraphed for him to rocket up that far down. Does Fox have safe multi-hits to make Ryu question using Focus Attacks? He has like 2 outside of a full jab combo, Fair and Dair. Uair can work, but when Ryu's on the ground? Good luck. Fair's not going to do much if he can't use it on the ground and Dair's going to get predictable. Falco on the other hand has Utilt, Up Smash, Nair, Fair, and jab. Does Fox space or plays footsies like Falco? Does Falco combo like Fox? Does Fox have the same throw options/setups as Falco? I could go on and on. Like I said, outside of Lucina, no character is just a strictly inferior character, especially if they play different. You can't even say Mario is a superior Dr. Mario when they're basically Melee clones who, unlike the Pits and Lucina and Marth, play differently and actually function differently than DP has an altered Neutral Special and a different Side Special or that Lucina is a gimmick of not having Marth's gimmick of tippers.
Also, as for damage output. When a character's average damage per hit is around ~10% and lowest damage outside of late hits, failed connections of multi-hits, incomplete jabs, and Specials is 9% and with late hits is 6%, that's still pretty freaking good when Fox's average is ~9% with lowest damage being 6% without everything else and 4% with late hits. Both are capable of comboing, but in the own ways just like everyone else. That pretty much means Falco has damage output. If he didn't he wouldn't be just an inferior Fox, he'd be the worst character in the game by a long-shot. This hasn't been updated since May, but it's still a good reference.
Also, at least 50% of the cast can't keep up with Ryu's weight since he's the 14th heaviest character. Pointing that out is kind of useless when several top/high tier characters are lightweights. Only Ryu, Ike, Mario, Sonic, Captain Falcon, and Diddy are middleweights and above. Sheik, Fox, Pikachu, Meta Knight, ZSS, and Rosalina are all lightweights.
Last, but not least, Focus Attack is at a minimum, frame 31 and at a maximum, frame 70. It can be dash canceled starting at frame 26 and while it has super armor, spamming that is going to lead to Ryu getting his head cracked open. A move that slow does not destroy anyone no matter how good of a move it is.
