214D is really good against people who throw themselves at you, i get haku's and ragnas with it all the time, after doing the IAD part i would keep the combo on the ground and finish with the BBB ender or CAB, or if you do take it into the air, dont double jump, just IAD j.CC > 5C > 2CC > j.CC > 236A > 214C. you can then charge with j.D and air dash j.CC for more pressure.
