Yeah, I've just been messing around in Training and playing against CPUs to get the feel for the characters. I can beat level 7 CPUs pretty consistently now after a short night of playing.
I've watched some aMSa videos, but I don't really know what to look for. He's moving so fast that it's hard for me to keep up.
Just watch for the basic things he does like how he approaches, what he does after a grab and things like that. Probably best not to focus too much on combos or crazy setups just yet when watching him
