Yo, i can tell your jin is tourney lv. There's not much anyone here can tell you about what to do. Be careful when jc-ing to continue pressure, when you meet that opponent who is not scared to AA, it's gonna be a hard habit to stop, in fight.
And i know you only missed and attempted this combo once, but work 623B combos, there the best.
Also, more 6A, but stock the rapid and the back-up B shory.
Also, i know the insane difficulty of properly capitalizing off of jin random miss positioned hits, but work on 5D-ing on landing, -4 is nonpunishable so... yea :3
oh and more max damage combos, i seen your combo movie, i know you have them, use them.
lol, sorry this is like my 6th edit, When i play my main (Hakumen) i make it a job to hurt people like you who rush in behind projectiles, pressure with air moves, and 6D. try not to 6D or people like me, will Critical Counter you, and kara throw you, and slip 623s into those 1 frame openings offline. keep that in mind when you meet one
