You play Kung Jin a little risky. Bf4 is punishable on block/full combo punishable when right next to the opponent. B214/b212+3 is your best string in the neutral. MB df2 is a good tool, plus on block. B243 is a good strong for mixup, don’t always gotta go for no swing of b14. That’s a hard string to hit confirm when going for mix.
I believe your optimal combos off your starters cancelled into bo swing are:
Mid screen: Run, 34, ia divekick, 34 xx db3
Corner: 4 xx bf4, 343 xx db3
Not too sure of optimal with meter. Don’t really play bojitsu. I can tell you everything you need to know about ancestral
