Rejoice Marth Mains! He now ONLY HAS half the landing lag compared to brawl! Cheers!
But you have to look further.
Nair, Fair, Uair, Bair, and Dair
Melee: 15, 15, 15, 24 iirc, 32. Dolphin Slash 34
Brawl: 8, 8, 8, 22 iirc, and 32. Dolphin Slash 34
Smash 4 1.0.0: 15, 18, 16, 19, 28. Dolphin Slash 23
Smash 4 1.1.0: 12, 16, 14, 17, 24. Dolphin Slash 20
In previous games we had Bair, Dair, and DS (and RCO lag in Brawl) as the equalizer. With those in the picture and the fact that most characters have nerfed landing lag from Brawl, 1.1.0 Marth's landing lag is actually fair and pretty perfect. He doesn't deserve less landing lag than this.
Now, his autocancel is another story. Marth's AC windows (I call them arrow slits) in this game are CRAP and need slight adjustments regardless of whatever other buffs he gets.
I posted this in the Marth thread, but since you brought it up, I'll say it here.
Unfortunately I don't have my 3DS 1.0.3 to test this. It's as simple as doing SH DB1 to Bair. I just tried it and the Bair hitbox doesn't come out. Marth lands on frame 6. So was it always like that? Someone needs to test whether Bair's hitbox came out after SH DB1 in an early version of the game. I have no idea why this would be nerfed so I don't know if I believe it. No one even used SH DB1 let alone the crappy boost in recovery it gave.
Moves like Sonic/Mario's Fsmash kill way too early in my honest opinion.. a move shouldn't be thhat safe and that strong on characters that have no problem comboing up percents.
You're right to complain about that. They have/had too much kill power for their shield safety. On top of that, Mario's sour spot is too powerful and Sonic's has too much range (doesn't match his fist at all). Now on Sonic the power reduction is pretty noticeable so I'm going to put Sonic's Fsmash is my book of fair but still really good Fsmashes now.
