Thanks for the feed back.
I do agree with you, I never considered forward up as the input till you brought it up but that would be a lot more intuitive. I defaulted to (down, forward, x) since that is the Hadouken input from street fighter. (Forward, up, x) may make the input more consistant too, since most times you will already be holding forward.
I will try adding it and see how it feels.
Thanks!
