Ninja will almost certainly benefit from Blood for Blood, if they can be smart and avoid damage. I could definitely see them pulling from Pugilist skills like Internal Release though.

Did they say anything about the weapons, in regards to if it's one weapon that fits both hands like Pugilist, or if it's one weapon for each hand for true dual weilding? And most importantly, can they equip the Fuma gear? They better be able to equip Fuma gear.
