Why would you nerf 33B? 33B is fine, its steppable and can be punished on whiff. What makes it imba is it damage on ch, in combination with SC5 backstep mechanics. But by nerfing FC3BB and JFT you automatically nerf 33B ch. Its way better to nerf the moves which are not intented to be used outside of combos than the actual combo starter. So i think Maxous nerf suggestions make sense.
I highly assume all would be damage nerfs, othwerwise you make the moves useless. 44B+K would be pure shit if it wasnt fast, just take away the stun animation, maybe give one guaranteed JFT. JFT also needs nerfdamage or simply take away the second JFT possibility. This way it stays usefull without beeing nerfed to shit.
