Hell yeah. I ain't got time to create set-ups with every damn character, lol. Except Hayabusa. I don't steal set-ups for him since his best set-ups are the ones I discovered. Other people keep stealing my Ryu stuff after they see me kicking ass with it, lol
Knowing other people's set-ups is always nice, too ,because then you know what to expect when fighting others who use that character.
I made up a bunch of Sarah set ups. I know they are mine becaus I'm the only one who uses her parry to get the stun I want lol. I usually don't use set ups, I just tend to poke at you until threshold, and I dont CB much, just launch and chip at your health
