Have a center hitbox on his sword that deals more damage and knockback than his hilt but less than his tip.
Tipper hitbox to be slightly larger.
Have reduced knockback on all throws but up throw.
Back hit of up air be fixed.
Have each hit the first three forward hits in Dancing Blade deal less knockback but slightly more hitstun.
I don't have time to explain but I will go more in-depth with edits.
