Cheers mate. FADC took me over a year to nail, I am a VERY slow learner at this game as Art will tell you, but overall I have steadily been improving.
Zoning - I am hesitant to throw many fireballs because of that very reason, I feel they will jump it and get an easy punish. I need to force myself to keep using mp.dp as AA and eventually I think I will be more confident throwing more fireballs. One thing you may notice, I was trying to stay just outside of his sweep/footsie range when he threw it and then do walk up throws which worked many times in that set.
Footsies - No excuses, I need to use that way more.
My biggest weapon now is jab! Before I would jab jab jab until they were out of range which is a waste, but now I almost always follow the jab jab through with hp.dp and even fadc > ultra if it is on. I can now finish off rounds where I previously would have thrown away. In training mode I have tried what you do which is cr.lk cr.lp cr.hp hurricane (followed by dp if in corner) and my timing for that is not spot on so I find it too risky in games, I'm sticking to what I know lol.
