Re: DC's New 52: Reviews and Discussion (Spoilers welcolme and likely)
Considering the "human in a bat themed suit" seems to be the only adult in the room with the NuJLA I'd take him over the other yahoos.
Aquaman and Wonder Woman haven't entered the room yet. Remains to be seen if their backgrounds in leadership ( they are after all royalty) factor into things and how "adult" they will be portrayed. Given Johns "Aqua-love" of late, Arthur might get the nod.
