(nobody said this was going to be Fair and balanced, so...)
Upspecial has bigger hitbox and kills earlier
Dspecial charge faster
Dspecial charge slower but It is the full super (Simply add tatsu and knockback if u dont want to lose time)
Special cancel and super cancel
More hitlag
Autoturnaround (Two braincells moment)
Taunting give damage up for ur next move only based on what taunt u are (First taunt=8%, second taunt=7%, third taunt=6% or lower)
Shinryuken has less knockback and doesn't have pratfall (shinryuken to shoryuken)
Dtilt Is faster
Ftilt Is faster
Utilt Is faster
He Jump much higher (even higher than the buff to his Jump that Idk of u putted already )

If*

True inputs (Just for the feelings)
Bigger hitboxes (even If they are already big but fairness doesnt exist like I said before)
Hadoken are faster,bigger and trascendent on the ground when used with the taunt charge and they use two taunt charge rather than One (only on the ground because we are Fair people)
Ken shouts takatte kina every time he do something (the First taunt crash the game with a big takatte kina (except the One at the start of the match))
Shoryuken Is fully invicible for the entire duration of the move but has more landing lag After the pratfall
The balancing of this things Is up to you or us
