Well, as it stands, the 66G bug prevents any CE from catching movement. It’s arguable that the bug should be removed, but in my estimation, the ratio of step-catching CEs that are smartly calculated versus those that are panicky and desperate is pretty low, and the game ought to avoid rewarding the latter variety of usage as much as possible. ZWEI's CE is a bit of an outlier, but CEs like Hilde’s, Yoshimitsu’s, and Elysium’s are already really strong even when their step-catching ability is nullified.8. CE frames changed from i22 to i19. -Improves the moves usefulness as a backstep catcher and whiff punisher.
Of course, a speedup for it would be useful for other things (like whiff punishing, as you mentioned). The question is whether the developers made it as slow as it is because doing otherwise allowed for use in combos that were considered too strong (like CE → 4A+B → CE → 4A+B or something).
