They just finished the 2nd reprints of the 1st batch of advent events (albeit 2 of the 2nd batch were released before Garuda). Either way, gonna be a long time before we get to the point (if we ever do) of getting FLB for those dual skilled ones. And they will probably just get their 2nd skill from small to medium, not a 3rd small skill.
Oh, and forgot that Ixion sword still doesn't have FLB, who knows what they will do about that.
