I'm VERY unhappy with how Foward-B Super Missiles turned out. It seems insane to have Super Missiles - THE killer move in Super Metroid - do 5% damage and almost no knockback more than regular Missiles.
Woo hoo, they home! See me waving my little flag? Yipee.
It seems a bit unfair to cripple all of her KO moves. Sure, she can smack you around nine times sideways with her high air manuverability, but Super Missiles should be slower, but harder hitting. Not just more damage. Kind of eradicates the point.
She's not awful but I'm disappointed with her KO power.
EDIT: It seems to me that Sakurai intended on making her less about KO power and more about getting them to Spike range, but then promptly forgot that when he designed the entire rest of the casts' UAir and UpB. Meh, I dunno, she's strange.
