Oh guys, apparently 2D has very little knockback, the following may well be legit:
CH 2D, 3C > AC, AC whiff, 6C > j.2C, 2B > 2C > AC, 2D
Not sure about the AC finish though. 2D CH, 3C already works even with 2D's current knockback. And it seems that both drivers have the same proration. Combos from both give damage exactly 1000 damage different.. The combo proration is completely arse however. No comment on 3C CH being techable or not. If it isn't then:
3C CH, 5B > 5C > 6A > AC.... is legit, even at range.
