The debuffs he gives in the extreme version are literally called "Force against Earth/Wind". To me that's indication enough of his elements actually.
If the design of the attacks shouldn't be taken into consideration then I'd doubt what element Bismarck belongs to. Or more extreme, what is Ramuh then?
