Normal Moves
All of Gouken's normal moves have been improved.
Close Standing Hard Punch and Close Standing Hard Kick have more frame advantage.
Close Standing Medium Kick has 3 frame start up start-up, so it'll be easier to compete against some of the other fighters.
Neutral Jump Hard Punch and diagonal Jump Hard Kick have pursuit properties, and will slam opponents into the ground.
Ranges on his normal moves haven't changed.
Back grab has been changed to deal gray damage, so the combo damage from the grab has been decreased. (Translator's note: They're probably saying that the back grab deals 0 gray damage, so it'll get scaled as a combo as well.)
Special Moves
In specials, Light Punch Running Palm (Senkugoshoha) has been drastically changed, so it will connect from weak attacks (Light Punch/Light Kick), and EX Hurricane Kick locks opponent, making it easier to combo.
Recovery of the Demon Flip Focus has been significantly decreased, making it easier to utilize.
Kongo (Counter) is changed as well. To be precise, it can only be activated now by using Punch buttons and the strength of the Punch changes where it sets up a counter hit at. Light for low attacks, Medium for middle attacks, and Hard for upper body attacks.
Other Stuff
During backdash, Gouken is now considered airborne right after invincibility ends.
Overall
His normal and special moves have been changed, and he will be able to do new things while retaining old tactics.
As a result, his 'easiness' might have been changed, but you will be able to enjoy strategies different from Ryu and Akuma.
