Am I the only one that doesn't like Shotoken characters all that much? I hope they leave him, Evil Ryu, Oni, and Gouken out of it
Today a shoto is merely a fireball+uppercut character, I believe. Which makes Sagat a shoto.
A shoto is fireball/dragon punch/tatsumaki, for this reason (and also his movespeed+normals) Sagat isn't really classed as shoto otherwise you'd have to class other characters like Rose as shoto too since fireball/soul throw/soul spiral function similar.
Gouken lacks a standard shoryuken outside of super/Ultra 1 and is replaced by a rush palm and his tatsu goes vertical. Also his normals are way different to the standard shoto list so he's not really one.
Sakura functions more like a shoto, you could argue she's borderline shoto because her specials move a bit different but they're closer to traditional style than others.
Funny thing about Dan is his "shoto" moves are designed to suck to match his unfinished training with Gouken, but his moves that are based off Muay Thai (Dankyaku and some of his normal kicks) are better due to his father Go Hibiki.
