Gouken
[Normals]
First of all, his normals are overall improved.
To be precise, his close s.MP and close s.HK have more frame advantages.
His close s.MK has 3f start-up, so it'll be easier to compete against some of the casts.
Also, neutral jump HP and diagonal jump HK have pursuit properties, and will slam opponents into the ground.
Ranges of the normals haven't changed.
Back grab has been changed to deal gray damage, so the combo damage from the grab has been decreased. (<- I believe they're saying that the back grab deals 0 gray damage, so it'll get scaled as a combo as well.)
[Specials]
In specials, LP Palm (Senkugoshoha) has been drastically changed, so it will connect from weak attacks (LP/LK), and EX Tatsu locks opponent, making it easier to combo.
Also, recovery of the Demon Flip Focus has been significantly decreased, making it easier to utilize.
Kongoshin is changed as well.
To be precise, it will come out in punches only, and strength of the punch changes where it kongos.
LP will take low attacks, MP will take attacks right in the middle, and HP will take attacks at the upper body.
[Others]
During backdash, Gouken is now considered airborne right after invincibility ends.
[Overall]
Normals and specials have been changed, and he will be able to do new things while retaining the old ones.
As a result, his 'easiness' might have been changed, but you will be able to enjoy strategies different from Ryu and Akuma.
