no need to go into defensive mode. he is “hard” to win with because he has barely any “gimmicks” to rely on and you have to “play tekken” with him.
i am sure you growed as a player overall over time, even tho i still have the feeling you overestimate yourself a bit to much, based on the last tourney you mentioned and that you really believed joe is the only one you need to worry about…which at the end from what i have seen didnt end so well for you.
learn what to do against her mixups strings, what are her options afterwards on block ect ect. she can go ham into you while having good tools to keep you away/punish you for attempts to go in. i dont know how you play now with her, thats more a overall leo s1 “rant”. i didnt know the mu so far and maybe the changes will make her less oppressive but at the end its still a char where you really need to learn the matchup. and yes, i agree that its a overall thing in this game that mu knowledge is very important but as i said before for some chars thats something you are really forced to or you get bopped by “gimmicks”.
