scratch this part. I’ve confirmed that holding back, up, or up/back, you can still FFchain. But holding those directions are pointless as far as any progression is concerned, atleast in my opinion.
The strong - fierce chain comes out when holding any direction but down, down/back, and offensive crouch.
Directions you can hold:
FF chain: :l:, :u:, :ub: back, up, up/back
strong - fierce: :l:, :r:, :u:, :ub:, :uf: back, forward, up, up/back, up/foward
Directions you can’t:
For both FF chain and strong - fierce: :d:, :df:, :db: down is the universal no chain direction for Guy.
Too bad, cause that limits the buffer zone alot I think. *note that it’s still very lenient though, you can still end up holding the “bad” directions if you time it properly.
This is why IMO it’s better to go neutral whenever you chain, that way there’s no risk of screwing up the chain and you aren’t making your motions longer(by using back making more inputs) comboing into his level 3 kick.
