Well, what can you do on 4d FC? a lot of things probably. Against characters who can't be haida looped i usually do something like
4D FC, d.2D (has to be 2 hits), d.5D, d.6A, d.6C, 214A, BnB ender... If my 4D FC at point blank range
If it hits a bit farther i think you can do something 4D FC, d.2D, d.6A, d.6C, d.5C, 2147A ect ect...
anyone got a better idea?
