its not a waste by any means if you could remember all of that then it would be a great benefit, but that's easier said than done. you should focus your attentions to where its needed
me personally i already have a good idea of Kasumi's, so instead i focus on Helena since she gives me the most trouble and i find her almost impossible to punish. i should also look at ryu's since his is oddly deceptive
I'm trying to learn everyone just cause people are starting to use different characters. I find helena and ryu so hard to punish too! They both freak me out lol
^ I think rig is scary because all of his frame traps, and bass is so slow but.... IDK. Maybe since barely anyone uses him that makes him unpredictable lol
