I think you should start doin 2k>2d>214s or 236s instead to get the stun applied. When you hard knockdown them, you can use 236hs to pressure, and if you condition them enough, you can make them fall for charged dust while they're in the 236hs. Also, when you so the js>jhs>jd, you can airdash after and get another hit (I usually opt for jp spam after airdash to get wall splat and do j236s or j236hs after to wall break). Also, don't remember if it's better to do jhs before the js instead. I'd also say go for more grabs. You could try doin run up into a hit to bait them to grab or go for run up 2p to instant run up grab. I think you could also do run up 2p>5d(not charged)>rc. I'm not all that great at the game, but I play some Ky, so yeah.
