Among these are other changes.
Pursuit Attacks - In Hunter Pursuit attacks do damage, whereas in Savior they do only white damage.
Bar - You can get up to 9 stocks of bar in Hunter, and in Savior (according to Training mode) you can get up to 99. Getting hit in Hunter does not give you bar.
Projectiles - The further away you are in Hunter, the less damage any projectile based attack does , regular, ES or EX.
Tech Roll - same but in Hunter you just press back or forward when knocked down. In Savior you press the same thing + any punch or kick button. Same mechanics, different input.
No taunts in Hunter
