Well, a jump homing attack probably will stop peaches d smash, but I'm pretty sure G&W can shield fast enough after a down tilt. And WD shielding towards Mario is not an ideal situation, I'm sure Mario players use fireballs to force this type of reaction out of there opponents anyways. Marth and Mario have a good shot at being better than sonic, but we wouldn't know right now in this undeveloped metagame, and just because wizzrobe dominated everyone pretty one sidedly does not mean sonic is op, wizzrobe is a good player, sonic is a good character, and no one has a clear grasp on the meta game vs sonic.
I just don't want a massive nerf that we are all gonna regret just because of one tournament, without his options sonic could turn into pretty ****ty character, they might as well start fresh and completely redesign him.
But a slight nerf would be ok
