I'm horrible at trying to Full Step. Or almost any combo requiring DC. I can barely do the Slash-Hazzard combo as it is. I guess it's all in the timing.
One advice: Full step needs a TDC or RDC. Basically it needs a clockwise direction towards the enemy, thus any of the RDC or TDC can be used.
I don't know if you play other fighting games, but the trick is when you go to dodge to do hop step do a half circle with joy stick.
Do a half circle left or right depending on which way you want to go.
I told anther friend to do, a half circle to land this now he do it like its nothing.
