In training mode, learn combos, but play a little bit of Arcade mode to get a handle of the character, or skip arcade mode and play online, but when you play and are on the offensive, try to do a combo that wouldn't put u at a disadvantage (eg you do a combo but your opponent can't counter with Ultra). Try not to do a lot of jump-ins since you can't block attacks in the air.
Oh and again I remind the proper use of Focus Attacks and proper use of EX moves.
Finally have fun and learn from your mistakes :)
Very awesome advice. I totally get what you mean about being jump cautious online. That's probably one of the primary ways people throw matches. And i'll practice combos all the time, but i'll only use the ones that I know i can pull off without any thought. I did finally figure out how to focus dash. I had no idea that to dash from a focus attack you HAVE to still be holding the buttons down.. cause if you let them go, the attack will be thrown. I still cannot do crazy juggles and airal ultra set ups, but i'm getting better. I was dominating for a good while last night with Cammy. I think i'll focus on her for a while and get back to Ryu another time. People are just able to predict him and Ken too well online.
[EDIT] speaking of Dhalism. I've fought some pretty nasty users online… he's really got an amazing control of the ground (if you know what you are doing)
