FA-Q.

Thanks for the info, that was one of the parts I was unclear on. Another is the old FA would replicate an attack, does the new FA do that? If I FA a (U)Straif will it replicate the attack at the FA damage, like 6 hits for FA damage or is it just one hit for FA damage?

1 hit, though you have 6 chances to activate it I think.

Only skills that have a variable number of hits/MP cost (e.g. Hurricane) can activate FA on every hit.
