Each fighting game is different buy generally it's all a timing issue. In blazblue, hit stun gets weaker the longer the combo in mk9 it's gravity, in sf it's links.
I don't play sfxT.
But usually there are input shortcuts, like ermacs lift is B,D,B 1.
I want to cancel d1 into lift. So I shortcut by doing B,D1,B1.
I dunno how sfxT works but look for Something like that.
